Description

6kV outdoor HV Ring Main Unit Description

It is a complete power distribution assembly suitable for 3.6~24kV, three-phase AC 50Hz, single bus sectionalized systems.It is mainly used for power transmission of small and medium-sized generators in power plants, power receiving and transmission in distribution systems and substations of industrial and mining enterprises, and starting of large high-voltage motors, so as to control, protect and monitor the power system.

The switchgear complies with IEC298 and GB3906-91 standards.In addition to the domestic VS1 vacuum circuit breaker, it can also be equipped with ABB VD4, Siemens 3AH5, domestic ZN65A, GE VB2 and other circuit breakers. It is an excellent performance power distribution equipment.

Product Advantages

The structure of the 12kV Switchgear Panel is bolt by aluminum zinc alloy board after the process of CNC machine tool and multi bending technology;
All the operation can be done after the Switchgear Panel door is closed;
High protection degree, protect the intruder of sundries and pests;
Simple and effective “five-prevention” lock function, protect error operation;
Can adopt VS1 and CD4 vacuum circuit breaker;
Easy replacement of the circuit breaker and free exchange of the drawers;
The Switchgear Panel can be installed by the wall, maintenance in the front, which reduces the floor space;
Large space of the cable room can connect many cables;
The relay room and the cable room can respectively add a heater to avoid freezing or erosion.
