TW Wire
Type of building wire used for general purpose at ratings up to 600 volts. It is designed to operate at temperatures up to 60°C (140°F) in wet and dry locations and is especially advantageous for rewiring as well as new installation. The wire is insulated with a PVC compound, designed to provide a tough wire that possesses excellent dielectric strength and is flame resistant. The smooth surface is treated with a silicone solution to ease pulling through conduit and ductwork.
