Vertical-break disconnect switch: up to 72.5kV and above, 630-3150A, lightning impulse 325-650kV, 3s short-time 20-40kA, making peak 50-100kA. For substation isolation duties.
Three‑phase group‑operated vertical‑break disconnect switch supports upright, vertical and under‑hung mounting with manual / motor operator, ground‑level operation via linkage‑pipe system. It follows ANSI C37.30.1 and is aligned with relevant IEC disconnect‑switch standards, project customisation available.
High-performance Side-Break Switches: Ensure safe, reliable high-voltage isolation for power systems. Easy to operate, durable—ideal for industrial, distribution, and utility use.
High-quality Vertical Vee Disconnecter: Ensures safe, reliable high-voltage circuit isolation for power systems. Durable, easy to maintain—ideal for utilities and industrial use.
RDS series disconnectors: up to 550kV, 4000A, 63kA. Low-friction, low contact resistance, dead-center interlocking, springless fingers, ice-breaking capability for extreme conditions.
It supports horizontal upright, vertical and under‑hung mounting configurations. Both manual operator and electrical motor‑driven operator are optional for three‑phase group operation.
Visual patrolling inspection every 6 months; routine de‑energized maintenance every 5 years; full periodic overhaul every 10 years. For harsh salt‑fog / polluted environment, shorten cycle to every 2 years.
Maintenance follows ANSI C37.30.1‑2011. Installation, operation and maintenance shall only be performed by qualified personnel trained for high‑voltage power equipment.
Clean contact surface with green Scotch‑brite pad, then apply thin even‑film C5‑A grease and wipe off excessive surplus grease.
