Belden EPDM1/0TWBULK Tinned Copper Hookup Wire, 1/0 AWG, 750 ft Spool, Black

To help this problem, a stearic solution is applied to the 43133 600V lead wire during the manufacturing process. However, many varnishes may still bond to the insulation unless other special coatings are applied. (Other slip coats are available at additional cost). Because most cleaning processes will remove these coatings from the EPDM lead wire, cleaning EPDM lead wire before using in the process is not recommended. EPDM's 43133 chemically cross-linked elastomer with excellent flexibility at high and low temperatures (-55 to 150 deg C). It has good insulation and dielectric strength, as well as excellent abrasion resistance and mechanical properties. EPDM also has better cut-through resistance than Silicone rubber, which it replaces in some applications. EPDM is compatible with most varnishes. After the dip and bake cycle, however, the varnish tends to adhere to the insulation because EPDM, unlike some rubber insulations, does not exude oils or waxes. As the lead wires are pulled apart for termination or flexed, the varnish cracks, sometimes tearing the insulation.
