XGN65 (HXGT10)-40.5 Indoor High Voltage SF6 Ring Main Unit

Note: The price shall be subject to the final quotation.

1. General

1.1Main purpose and application range

XGN65(HXGT10)-40.5 type SF₆ Ring Main Unit（bellow short for Ring Main Unit）, is 50Hz AC three phase indoor HV distribution equipment. Load switchgear、 earth contact and busbar for circuit are sealed in metal enclosure. It is a composite apparatus which adopt spring operation device and use SF₆ as distinguished arc and insulating medium. It is suitable for 40.5 kV power supply and ring power supply and double radiated power supply, which can change the previous ways of one-way radiated power supply. When circuit broke out fault, loss current for transformer circuit can recover in time, so it can improve reliability and frequency of power supply especial for commerce zone or countryside area. Meanwhile, ring main unit is convenient to use, not easy to influenced by weather, easily equipment, free maintenance, small volume, so it can applicable for box type transformer substation, load –breaking switch of ring main unit or switch-fuse composite apparatus by separate.

2. Technical Parameter

Note: Easily to influenced environment and radiating. Product need to choose for lowed capacitor, scope is about 30%.If rated current is lower than 10A,will not be lowed capacitor.(ex: rated current 50A fuse, actual current is 50*0.7=35A in fact)
