12kv AC Indoor High Voltage Ring Network Switchgear (Ring Main Unit)
China 12kv AC Indoor High Voltage Ring Network Switchgear (Ring Main Unit), Find details about China Ring Main Unit, Rmu from 12kv AC Indoor High Voltage Ring Network Switchgear (Ring Main Unit)
Overview
SF6-insulated ring main unit and SF6-insulated compact switchgear are used in medium voltage distribution networks. They offer a sealed stainless steel tank which contains all the live components and switching functions. The transformer is protected either by a switch fuse combination or a vacuum circuit breaker.
SF6-insulated ring main unit can be supplied as a 2, 3 or 4-way unit in standard configurations with additional equipment according to customer specification.
SF6-insulated compact switchgear has a unique flexibility due to its extendibility and the possible combination of fully modular and semi-modular configurations, with a maximum of 5 modules in one SF6-tank.
The units are delivered from the factory ready for installation. Routine tests are carried out on all units/ modules before dispatch. No special tools are required for installing the equipment.

Our Advantages
(1). Energy conservation: Farady voltage regulating type capacitors will change the output reactive power by regulating voltage on capacitors, so that the reactive power can be adjusted smoothly. Comparing with other method, it can ensure the capacitors in best condition, the energy saving effect is much better(2). Low cost:If the old power transformer substation need to reform, only need to add a voltage regulator between the circuit breaker and capacitors, the original circuit breakers, reactors, capacitors can be reuse, greatly reduce the cost of transformation
(3). Maintance Free:When traditional circuit breaker and contactor switching, switching devices and capacitors often damaged because of the above problems, result in high maintenance costs, using Farady devices, automatic control reactive power output, there is no potential risks of other equipments, greatly reducing maintenance and staff costs in power transformer substation
