HW310: 5kV CCW Shielded Cable, Type MC-HL

LifeGuard™ Low Smoke Zero Halogen* cable is for use in power, control and lighting circuits in a broad range of commercial and industrial applications. The impervious armor provides maximum conductor protection and prevents the entrance of water, gas and corrosive elements into the electrical core. The LifeGuard™ jacket is highly flame retardant, produces very small amounts of smoke when burned and contains no halogens. It is ideal for applications where a high degree of safety and equipment protection is required.
