GW13-36 Isolating Switch

The GW13-36 Isolating Switch is a high-voltage outdoor disconnect switch purpose-built for 36kV overhead distribution networks. Operating as a manually actuated isolating device, it provides visible circuit separation for maintenance safety and network sectionalizing. With a rated current of 630A and peak withstand current of 50kA, the switch is engineered for robust fault-handling capability. Its defining feature is the 160-degree blade opening angle, offering superior visual verification of open-circuit status. Available with either porcelain or polymer insulators and built on a hot-dip galvanized steel base, the GW13-36 is ideal for utilities and industrial operators requiring rugged, standards-compliant isolation equipment for medium-voltage outdoor applications.

◆ High short-circuit withstand rating of 20kA for 3 seconds
◆ Peak withstand current capability of 50kA
◆ Dual insulator options: porcelain for traditional applications or polymer for lightweight durability
◆ Silver-plated copper blades and terminal pads for optimal conductivity
◆ Self-locking mechanism prevents unintended operation
◆ Hot-dip galvanized steel channel base with excellent outdoor corrosion resistance
◆ Compatible with optional loadbuster hooks for load-breaking capability

● Superior Visual Verification: The 160-degree blade opening provides an unmistakable visual break, significantly enhancing operator safety during maintenance procedures.
● Heavy-Duty Fault Handling: With 20kA short-circuit withstand and 50kA peak withstand ratings, the switch remains stable and undamaged under severe fault conditions.
● Proven Insulation Performance: Lightning impulse withstand of 170kV and wet/dry power frequency withstand voltages ensure reliable insulation coordination in exposed outdoor installations.
● Material Excellence: Silver-plated copper current path minimizes contact resistance, reduces hot spots, and extends operational service life.
● Heavy Pollution Readiness: Designed for heavy pollution environments, making it suitable for coastal, industrial, and high-contamination zones.
