High-Temperature Lead Wire

Tempco LDWR-1011 is an 18 AWG nickel-clad copper wire insulated with fiberglass and mica. It is designed for electrical and industrial installations that require reliable operation at elevated temperatures. The natural colour jacket provides easy visual identification in complex wiring looms.

100-Foot Length and 600-Volt Rating

The 100 ft spool supplies ample length for panel wiring, appliance leads or heating-element connections rated up to 600V AC. The insulation withstands continuous exposure up to 842 degrees F, beyond which the mica and fiberglass may degrade and the conductor can oxidise.

Nickel-Clad Copper Conductor

The nickel cladding protects the copper core from oxidation at high heat, eliminating the need for separate high-temperature terminals in many MG-designated applications. The construction fits standard 18 AWG ferrules and terminals, freeing the installer from sourcing specialised connectors.

Questions about this item

Will this 18 AWG nickel-clad copper wire carry 600 V AC alongside older 600 V-rated cables in the same conduit?

Yes — the MG designation, fiberglass-mica insulation and 600 V AC rating match common 600 V cable specs, so it can share conduit with existing 600 V-rated wires of the same voltage class.

How can I verify the 842 °F temperature rating is holding after installation?

Measure the conductor temperature under full load with a calibrated thermocouple; it should remain at or below 842 °F if the wire is performing to its MG rating.

Does the 100 ft spool include any terminals or connectors, or must I buy them separately?

The spool supplies only the 18 AWG nickel-clad copper wire with fiberglass-mica insulation; terminals, connectors or sleeving must be purchased separately.
