EXAR® 155 SFX UL3575 (Metric)
EXAR® Oil Resistant SFX 7.5Kv is the superior flexible and heat-defying cable in its class. This innovative 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.
