15kV European Tee Type Surge Arresters
Product Introduction
It applies to 6/10kV, 8.7/10kV, 8.7/15kV switchgears to protect power transmission equipments and components from lightning overvoltage and switching overvoltage.
Technical Features
1. Adopt zinc oxide resistor coer to ensure grid operation safety.
2. Integrative injection molding with good waterproof function.
3. Compact and flexible design applys to compact switchgear.
4. Fully-screen design in surface, screen resistance is less than 5kΩ.
