Thermocouple Wire - Thermocouple Wire Constructions

Constructions are arrangements of the conductor and insulation that suit the application. For instance, singles can be used to wire panels more easily than a jacketed construction. And duplex constructions can be more easily used in conduits. And twisted duplex constructions are more flexible than paralleled ones and counteract flux induced noises. Twisted and shielded constructions provide the best noise reduction.

Insulated Duplex Conductors - Twisted with Mylar-backed Aluminum Shield, Drain Wire, and Overall Insulation Jacket

Protective metal overbraids are used to enhance abrasion and cut-through resistance. With an approximately 85% coverage they also provide a noise shield although not as effective as the aluminized mylar tape full coverage shields.
