Outdoor line disconnectors RLNMD-LE, RLMDz-LE, RLNMR-LE are designed for:
- making clearly visible open gap for safe service assurance;
- switching curentless HV sections under load;
- deenergized sections earthing by means of stationary earthing device;
- switching transformer no-load current
Applications
Disconnectors RLNMD-LE, RLMDz-LE, RLNMR-LE are used for universal utilization in alternating-current of voltage 50 Hz open substations, network compartmentation and consumer segregation without load current for clearly visible open gap
