Brochure · EN — Siemens Energy Brazil brochure (2022) for air-insulated high-voltage disconnectors and earthing switches manufactured in Jundiaí, Brazil: seven disconnector families — EVL (vertical opening), DAL and RDA (double lateral opening), BC (centre opening), EVR (reverse vertical opening), LAV and LAH (semi-pantograph) — plus the GTF and TC earthing switches and the 3DV8 operating command, spanning 72.5 kV to 880 kV with nominal currents up to 5,000 A and 1-second short-time withstand up to 63 kA. Complements the SHVC (Hangzhou) 3DN0–3DN9 disconnector portfolio brochure in this library: both describe Siemens Energy AIS disconnector/earthing-switch ranges, from different manufacturing locations with different type designations.
Siemens Energy has a business unit specialized in manufacturing high-voltage disconnectors and earthing switches for open-air substations. Through personalized service it offers customers technically and economically optimized solutions, developed from an extensive high-voltage disconnector portfolio and associated services. The products have passed the most rigorous tests, with quality assured by ISO 9001 — guaranteeing full functionality along decades, proven by the varied applications already installed and fully functioning in Brazil and worldwide.
Siemens Energy is the main producer of disconnectors and high-voltage earthing switches in Brazil, counting on more than 80 years of experience inherited from SIEMENS. Its factories use the most modern production technologies, which together with a highly skilled team assure product quality and safety; in line with the global sustainability commitment, its processes combine high productivity and sustainability.
On performance, Siemens Energy disconnectors keep operating in Brazil and over the world: the portfolio includes solutions capable of operating under extreme environmental conditions — applications designed to work under seismic tremors, ice loads up to 20 mm and temperatures ranging from -50 °C to +50 °C.
The brochure lists the portfolio's shared strengths: subsets already assembled and preset from the factory; for each disconnector the moving part of the main blade is individually tested; easy assembly and commissioning on the substation site (intuitive assembly with an instruction manual); silver-made contacts — a highly conductive, self-lubricating material demanding less maintenance; permanent and agile technical assistance; technical support for the entire disconnector service life; and products recyclable at the end of their service life.
A two-page matrix (brochure pages 5–6) maps each product family to its nominal current In (A) per voltage level, alongside rows for Is, It (1s) and In (3s). Fidelity note: in the printed matrix only the In values below are populated — the Is, It (1s) and In (3s) rows are left blank for all families except DAL, which additionally prints an It (1s) value of 40 (kA) at 72.5, 145 and 245 kV; blank cells are reproduced as empty here. TC and GTF (earthing switches) are marked 'Not aplicable' [sic] in the 72.5 kV row.

The shared contact system is characterized by: contact force that increases during short-circuit; stable contact force throughout the entire service life; a silver surface giving better electrical conductivity and working as a lubricant; few pieces; resistance to an ice layer up to 20 mm; and maintenance-free operation for 20 years under normal conditions of use.
Arc restrictors can be supplied for all types of Siemens Energy disconnectors. With this accessory, disconnectors are capable of maneuvering the induced currents during busbar transferences: during the switching operation from bus 1 to bus 2, the existing potential difference causes an electrical arc between the disconnector contacts. Annex B of IEC 62271-102 describes the maneuver loads that appear under a busbar transference without interruption; the Siemens Energy arc restrictors for bar transfer are type-tested with more than 100 operational cycles of establishment and interruption of current.
The exclusive 3DV8 command assures wide space for cables and connections and has protection against condensation. Easy to use, it can also be safely manually operated. Easy to assemble and to maintain, the 3DV8 command demands revision only after 1,000 maneuvers.
The EVL disconnector is constituted by three insulating columns: two fixed (supporting the fixed contacts) and one rotative (moving the movable contacts). Due to its vertical opening it allows a small distance between phases; the locking system with double kinematics assures excellent contact even with over 50 kA short-circuit; designed lifetime is over 30 years. Available attachments: earthing switch and bus transfer. The arrangement can be side by side or aligned, adaptation for higher nominal and short-circuit currents is possible, and the modular design allows future installation of the attachments.
Each pole is mounted over a compact galvanized steel base designed for high mechanical loads, with high-quality maintenance- and lubrication-free bearings. Contact occurs by a double-kinematics system: during closing the first movement approaches the contacts and the second locks them — the contact force is generated by the blade rotating around its own axis before the blade is locked. This system requires low torques, making the movement smoother.

The DAL is constituted by three insulating columns — two lateral fixed and one rotative at the center. The central column supports the main blade and the lateral ones support the fixed contacts. It is ideal for substations where the space between phases is limited; the contact system is built with few components, offering low electrical resistance during maneuvers; designed lifetime is over 30 years. Available attachments: earthing switch and bus transfer, with the same side-by-side/aligned arrangement flexibility and modular upgradability as the rest of the family.
Each pole is mounted on a compact galvanized steel base with maintenance- and lubrication-free bearings. The main contact system is constituted by a pair of contact fingers on each side of the main blade, and the bus transfer is fixed directly at the terminal.

The RDA is constituted by three insulating columns, two lateral fixed and one rotative at the center. It is ideal for substations where the vertical space between phases is limited; the main blade is built with steel tubes for greater robustness of the live part; the contact system uses double kinematics; and it offers a high operating interval before decommissioning. Available attachments: earthing switch and bus transfer, with the family's arrangement and upgrade flexibility.
Each pole is mounted on a compact galvanized steel base with maintenance- and lubrication-free bearings. The opening and closing occur with a double-kinematics system assuring contact safety even in short-circuit: during closing, the first movement approaches the contacts and the second locks them — only after locking is the torsion spring released, making the main blade rotate and strongly grip the contacts.

The EVR is ideal for uneven busbars. It is constituted by two insulating columns — one fixed and one rotative supporting the main blade — plus another fixed insulating column which is inverted. The locking system assures contact even during 40 kA short-circuit, and the disconnector can be directly connected to the busbar, dismissing the inverted insulating column. Available attachments: earthing switch and bus transfer.
Each pole is mounted on a compact galvanized steel base with maintenance- and lubrication-free bearings. The contact system consists of fingers that fit and are locked by a double-kinematic system: during closing the blade makes two movements — first approaching the fixed contact, then rotating — so that on reaching the fixed contact the blade is locked and its adjustment is completed with the rotation, making the contacts firmly locked.

The LAV is an ideal disconnector for uneven busbars, constituted by two insulating columns — one fixed and one rotating, sustaining the main blade — and another fixed insulating column that is inverted or directly connected to the busbar. It has a lower space requirement in the horizontal direction; the clamp locking system ensures excellent contact even during short-circuits up to 40 kA; and the fixed contact can be mounted directly on the busbar. Available attachments: earthing switch and bus transfer.
Each pole is mounted on a compact galvanized steel base with maintenance- and lubrication-free bearings. The contact system is made up of clamps that lock firmly at the end of the movement: the clamps are spring-locked in a double-kinematic system — during closing the first movement brings the contacts together, and from a certain point close to the busbar the second movement starts to close the clamps, locking them firmly at the end.

The LAH is constituted by three insulating columns — two fixed (busbar connection) and one rotative (movable contact). It offers individual levelling by pole, assuring stability and perfect leveling of the set; it was designed considering all shorting, operating and conductor efforts; and the perfect balance of the main blade assures a complete, smooth and stable maneuver. The arrangement can be side by side or aligned, with adaptation for higher nominal and short-circuit currents and modular installation of attachments.
Each pole is mounted on a compact galvanized steel base with maintenance- and lubrication-free bearings. The contact system is made up of fingers that are firmly attached at the end of the movement; the shape and number of fingers are specifically designed to ensure better locking with an excellent electrical connection.
