1. What is SIS Wire?
SIS Wire (Switchboard Instrumentation Wire), commonly known as SIS cable, is a high-performance, single-conductor wire designed for use in switchboards, control panels, and electrical enclosures. Key characteristics of SIS wire include:
Rated for 600 volts, ideal for control circuit wiring and power distribution systems.
Heat-resistant insulation, with a temperature rating of 105°C or higher.
XLPE (Cross-linked Polyethylene) insulation that offers excellent dielectric strength and flame resistance.
Compact and easy-to-install design, well-suited for high-density wiring environments.
SIS cable is a preferred choice in industrial automation, power management systems, and commercial electrical panels where reliability and safety are paramount.
