RVB outdoor live-tank vacuum circuit breaker: 24-40.5kV, 1250-2500A, lightning impulse 170-195kV, 3s short-time 25-31.5kA, making peak 63-80kA. For outdoor substation distribution-line protection.
RVB adopts SF₆‑free & oil‑free vacuum arc‑extinguishing technology, offering solid‑encapsulated pole and porcelain‑housing insulation, maintenance‑free spring mechanism with 10 000 mechanical & electrical operations, optional built‑in CT and custom‑made service. It complies with IEC 62271‑100, IEC 60068‑2‑30 and other IEC standards for harsh outdoor conditions.
Outdoor live tank vacuum circuit breaker for 24kV, 36kV, 40.5kV and 52kV systems, offering reliable, maintenance-free protection for overhead lines.
40.5kV RVB Series outdoor VCB, 3150A, 40kA breaking. IEC 62271-100, E2 class, spring mechanism, IP55. Substation & distribution.
Reliable manufacturer of 36kV outdoor high-voltage vacuum circuit breakers for durable and maintenance-free switching in harsh environments.
Compact solid‑encapsulated pole for space‑limited projects; heavy‑duty porcelain‑shell type for main‑grid demanding environments. Both adopt vacuum interrupter without SF₆ and oil.
Optional built‑in/ external metering & protection CT, shunt trip coil, special creepage‑distance design, high‑altitude & extreme‑temperature adaptation. Custom‑manufacturing and full‑set design‑assembly‑test solutions are available.
Standard max altitude 1000 m, operating temperature ‑25℃~+40℃. For altitude＞1000 m, insulation reinforcement must be consulted with manufacturer at order stage.
