Champlain Cable | EXAR® SFX-OR Motor Lead Cable | 600V & 7500V in stock and ready for you!

EXAR® Oil Resistant SFX is the superior flexible and heat-defying cable in its class. This innovative new irradiation cross-linked polyolefin insulation combines the oil resistance of EXAR 150 with the flexibility and rubber-like feel of SFX. You can count on the same thermal, size, toughness, and varnish release advantages of the original SFX, plus a UL approval for use in oil up to 60°C. SFX can now be the one lead wire you use for multiple applications and environments. EXAR® SFX is the ultimate lead wire value in the motor and transformer market.

  • Highly Engineered Exar SFX-OR Irradiation Crosslinked Polyolefin
  • Excellent Flexibility
  • AWM, CL 1251 & 1503
  • Won’t Melt, Creep or Flow
  • “Best-In-Class” Varnish Resistance
  • Excellent Flame, Oil and Chemical Resistance
  • Thin OD Yet Tougher than Other Motor Leads
  • “All-In-One” Performance: Flex + Temp + OD + Varnish
