Reasonable Price for 24kv Indoor Use High-Voltage Isolating Switch-Yfgn-24
Model No.: YFGN-24/630
YFGN-24/630 indoor AC HV disconnector is applied at the site with rated voltage of 24kV and rated frequency of 50Hz. It is a switch with obvious safe isolating fracture designed and developed independently according to GB3804, guaranteeing the system safety accordingly. Such model of disconnector has features of small size, simple but reasonable structure, small operation force, reliable performance and convenient maintenance, ect. It can be use with 24kV HV Circuit Breaker in the cabinet and it is a HV disconnector with advantageous cost performance.
Note: The sensor with live display can be used for the switch insulator.
