MTW Wire

MTW (Machine Tool Wire) wire consists of stranded, bare copper conductors insulated with polyvinyl chloride (PVC). The stranding gives the wire more flexibility for routing in tight spaces such as electrical cabinets and the PVC provides heat and moisture resistance with flame retardant compound per UL 1063 and UL83. MTW wire is rated 600 V for machine tool and appliance wiring applications.

MTW vs MTW/TEW:  TEW (Thermoplastic Equipment Wire) wire is made with tinned, stranded copper conductors. MTW wire is made with bare copper conductors. The bare copper is more cost-effective, however, the tinned copper assists in the soldering process during installation and helps prevent corrosion.

MTW vs THHN: THHN (Thermoplastic High Heat-resistant Nylon) consists of a stranded or solid, bare copper or aluminum conductor with a thermoplastic insulation and a nylon jacket. Although both MTW and THHN are well suited for similar applications, THHN wire’s nylon jacket causes it to be less flexible than MTW wire.
