Heat-resistance class 120℃Heat resistant Wires

TESSX
Very Thin Cross-linked Polyethylene Insulated Heat-resistant Low-voltage Wires for Automobiles

T : Tinned conductor   E : Polyethylene  SS : Super thin type  X : Cross-linked
Fume Characteristic
APPLICATION Wires used in low voltage circuits requiring heat resistance (120 ℃) such as automobiles (Vehicles and motorcycles).
FEATURES TESSX wires have the same construction as AESSX wires, but are provided with tinned conductors to ensure better connectivity for terminals than AESSX wires.
