These series Ring Main Unit is extensible, SF6 insulated switchgear, with reated voltage of 12&24KV. All its HV live parts are contained in an air-tight gas tank, which is made from stainless steel of 3mm. The whole switching assembly is SF6 insulated, any free from any external influence, ensuring it great reliability of service and maintenance free. By plug-in type busbar extension, the series RMU can be of free combination and full modularization. The busbar extension has passed type test for power and thermal stability, and is fully insulated and shielded, exhibiting high reliability and safety.
The series Ring Main Unit is suitable for all MV network up tp 24KV, all compact power stations, power distribution substations in all important industries, such as petrol-chemical industry, metallurgical and mining industries, and all transformer substations and wind power system.
Technical Date for 24KV Ring Main Unit
Notes:
①Rated current of Switch-fuse panel depends on rating of fuse, and ≤100A.
② Rated short-circuit breaking/making current of Switch-fuse panel depends on rating o fuse.
*Value in brackets are for special requirement, please contact us for more information. If 20KA/4s is required for rated short time withstand, please specify definitely when you are ordering.
