GW13-15 Isolating Switch
Product Overview
Product Overview
The GW13-15 Isolating Switch is a manually operated disconnect switch engineered for outdoor overhead distribution systems. Designed for circuit sectionalizing and isolation at voltages up to 38kV, it delivers dependable performance with rated currents of 400A or 630A. Available in both 12kV and 36kV versions, the switch features a self-locking mechanism and a 90-degree blade opening for clear visual isolation. Constructed with silver-plated copper components and your choice of porcelain or polymer insulators, it meets IEC 62271-102 standards and operates reliably in heavy pollution environments at altitudes up to 1000 meters and ambient temperatures up to 40°C.
