GN19-12 10kV Indoor High Voltage Disconnecting Switch / 3-Phase Isolator Switch for Cabinet Power Distribution System
Category:
High Voltage Switchgear
Description:
Product Overview
GN19-12 series indoor high voltage disconnecting switch is a three-phase AC 50kV isolation device rated at 12kV (10kV system), widely installed inside XGN, GG-1A and other medium voltage switch cabinets.
It is used to create visible isolation breakpoints under no-load conditions, safely separate power circuits during equipment maintenance, overhaul and troubleshooting, effectively protect construction workers from electric shock risks.
Adopts vertical rotary knife structure, high-strength white ceramic insulator, thickened galvanized steel frame and copper conductive contact, stable mechanical performance, strong short-circuit withstand capacity, suitable for long-term continuous operation in indoor power distribution stations, factory power rooms, photovoltaic box substations and industrial complete set equipment.
Core Advantages
1.Visible Isolation Gap, Safe Maintenance Guarantee
Three-phase independent rotating knife switch forms clear visual isolation breakpoint, fully meets international power safety standards, prevents accidental power transmission during equipment maintenance, greatly reduces electric safety hazards.
2.High-Quality Ceramic Insulator
Anti-pollution, anti-aging, high insulation strength, stable performance under humid, dusty indoor environment, no flashover risk, long service life compared with ordinary silicone insulators.
3.Optimized Conductive Structure, Low Temperature Rise
Gate-type thick copper knife blade expands heat dissipation area; integral electroformed static contact with multi-piece contact finger design, large contact area, low contact resistance, excellent dynamic and thermal stability when short-circuit current passes.
4.Durable Galvanized Metal Frame & Mechanical Mechanism
Whole base frame adopts hot-dip galvanized steel, anti-rust and anti-corrosion; matched spring operating mechanism, smooth switching action, stable mechanical interlocking performance, support manual CS6-1 operating handle linkage.
5.Global Standard Compliance & Local Certification Support
Designed for 50Hz power grid (match Turkey, Central Asia, Southeast national power frequency), fully implement IEC 62271-102 international standard. We can provide EAC TR CU certification documents for Kazakhstan, Belarus; TSE test reports for Turkey, convenient for overseas customs clearance and local power grid acceptance.
6.Complete Current Specification Options
Standard models: GN19-12/630A, GN19-12/1000A, GN19-12/1250A; double-throw dual power supply type GN19-12ST available for special dual-circuit distribution projects.
