ROCKWILL RHB‑330 outdoor horizontal‑opening disconnector is rated 33 kV. Complete electrical ratings including rated normal current, lightning impulse, short‑time withstand & short‑circuit making current shall refer to its full datasheet.
ROCKWILL RHB‑330 outdoor horizontal‑rotation disconnector applies robust aluminium alloy terminals, heavy‑duty mechanical load capacity, horizontal opening layout for 33 kV outdoor substation. It shall comply with IEC 62271‑102, and IEC 62271‑1 general specifications.
Live tank SF6 gas circuit breaker for 40.5kV to 363kV systems, delivering reliable, high-performance protection for transmission and substation applications.
UHV live tank SF6 circuit breaker for 1100kV, delivering reliable protection for ultra-high-voltage transmission and bulk power systems.
High Voltage Live Tank SF6 Circuit Breaker for 550kV transmission, providing reliable protection and switching for extra high-voltage grids.
RHB‑330 adopts horizontal‑opening (horizontal‑rotation) disconnector structure, equipped with operating mechanism support bracket, widely deployed in outdoor 33 kV substations.
Foundation shall bear static load: horizontal 50000 N, vertical 80000 N. Height difference between each base surface shall not exceed 2 mm, foundation self‑weight shall be considered during civil design.
Please advise your project requirement. We can provide combined disconnector‑earthing‑switch version subject to project specification and type‑test report.
