“The flexible choice for heavy-duty industrial powerengineered with premium silicone rubber and a protective glass braid for maximum reliability up to 200C.”

Why Professionals Choose SRML Motor Lead High Temp Wire

The 1 AWG SRML wire is engineered for high-amperage industrial applications where extreme thermal stress and constant mechanical vibration are the norms. It is the premier choice for large motor leads and heavy-duty industrial apparatus. The specialized silicone rubber core remains flexible in freezing temperatures as low as -60C and maintains its integrity in heat up to 200C.

• -60C to 200C Heat Resistance: Rated for continuous use in extreme thermal environments up to 600 volts, providing a higher thermal ceiling for heavy-duty power circuits.

• High-Strand Flexibility: With 259 individual strands of tinned copper, this 1 AWG wire offers a significantly tighter bend radius than standard building wire, making it easier to install in cramped enclosures.

• Tough Fiberglass Jacket: The outer braid is impregnated with a flame, heat, and moisture-resistant compound, providing a rugged defense against abrasion.

• Tinned Copper Conductor: Soft-drawn tinned copper prevents the oxidation that leads to terminal failure in high-heat settings.
