GW4-40.5(D)(W)
Adopting a double-column horizontal rotary structure and high-quality copper-tungsten conductors, the switch delivers low contact resistance, high conductivity and stable current carrying capacity. It effectively avoids overheating and ensures safe, efficient power grid operation.
Fitted with high-strength anti-fouling insulators with extended creepage distance, the disconnector features excellent insulation and anti-interference performance. It adapts to humid, high-altitude and polluted areas, ensuring reliable circuit isolation during maintenance.
All metal parts are hot-dip galvanized for strong rust, oxidation and salt fog resistance. The optimized outdoor structure withstands harsh weather, enabling stable all-weather outdoor operation.
Equipped with anti-misoperation interlock devices, this switch supports manual and electric operation. It boasts high mechanical strength, easy installation and low maintenance, reducing operational costs for power grid projects.
Ideal for 40.5kV high voltage power systems, this outdoor disconnector features stable performance and strong environmental adaptability. We provide global clients with factory direct supply, complete certifications and professional after-sales service.
Product Details
GW4-40.5(D)(W)
Outdoor high voltage AC disconnector
□Meaning of type
□Introduction
□The GW4-40.5(D)(W)disconnector is a kind of HV outdoor electric equipments used in three-phase AC50Hz electrical system.It is used for switching
-on/off the HV circuit when there is no load in the circuit in order to change or transfer the circuit and also disconnect the current with the bus bar, breaker or any other HV electrical equipments when overhauling the circuitry.
□The disconnector is a double-post plane interrupter mid-openedt ype.It can match ground switch on 1 or 2 sides.It uses CS14G、CS17G or Cs11 manual operating mechanism or CJ series electromotor operating mechanism to realize three-phase linking operation.The ground switch uses CS14G、 CS17G manual operating mechanism to realize three-phase linking operation.
□The disconnector conforms to the standards of GB1985-2004,DL/T486-200X,GB/T11022-1999,DL/T395-2006.It also meets thewhich is constituted for the Sate Grid Corporation of China.
