Full technical specifications on each product page. Over 500 items available for supply on request.

ARME-AIS — Air Insulated Modular Switchgear
Air insulated metal enclosed modular medium-voltage switchgear. Ten functional cell types, IAC-AFL internal arc classification, IP3X degree of protection.

ARMC — Metal Clad Switchgear
Metal clad medium-voltage switchgear with earthed metal partitions, withdrawable vacuum circuit breaker and IP4X protection. Incoming, outgoing, coupling and metering cells.

ArmAir — SF₆-free Switchgear
Environmentally friendly medium-voltage switchgear with dry air insulation — no SF₆ greenhouse gas. Compact design for networks up to 24 kV.

ARCK — Monoblock Concrete Kiosk
Monoblock reinforced-concrete transformer substation for distribution and generation applications. Equipment and internal earthing assembled and tested at the factory.

ARSK — Sheet Metal Kiosk Substation
Lightweight weather-resistant substation made of galvanized powder-coated steel. Project dimensions from 2 to 40 m, separate MV, transformer and LV compartments.

ARPK — Prefabricated Concrete Substation
Distribution and transformer centers assembled from factory-made precast concrete panels — for facilities larger than monoblock kiosks.

Mobile Distribution and Transformer Substation
Trailer-mounted substation for emergency, temporary or remote power supply. Commissioned many times faster than a fixed substation.

SF₆ Gas Insulated Disconnector
Gas insulated disconnector for 12–36 kV systems with high dielectric strength across the isolating distance — 145/195 kV.

SF₆ Gas Insulated Circuit Breaker
Medium-voltage circuit breaker with SF₆ as the interrupting medium. M1/E2 endurance classes, peak withstand up to 50 kA.

Front-Operated Vacuum Circuit Breaker
Maintenance-free vacuum circuit breaker with front-operated mechanism for switchgear assemblies. M2/E2/C2 classes.

Side-Operated Vacuum Circuit Breaker
Compact vacuum circuit breaker with side-operated mechanism — for reduced-width cells with high breaking capacity.

ARCT-KA07 — Cable Type (Toroidal) Current Transformer
Cast-resin ring-type current transformer for metering and relay protection of cable connections. Primary currents from 40 to 4,000 A.

ARCT-B — Block Type (Support) Current Transformer
Cast-resin support-type current transformer for medium-voltage cells — measurement, metering and relay protection.

ARVT — Block Type Voltage Transformer
Cast-resin voltage transformer for metering, measurement and protection functions in medium-voltage networks. Available with and without fuse.
