> **1** Additional Type J insulated wires are available. See Fused Tape Insulated **TFE-J** and **KK-J** Series. 

**†** Weight of spool and wire rounded up to the next highest lb. (does not include packing material). **††** Overall color clear 

***** Has color tracers on jacket and conductors. 

****** Has trace thread in Positive leg, Negative leg is red, overall has trace thread. 

****** * Two insulated leads bonded together, but with no overjacket. 

Some wires available with Special Limits of Error; consult Sales for pricing and availability. 

## **Ceramic Weave Note:** 

**XC** standard ceramic insulation with maximum insulation density. **XT** more tightly woven with reduced insulation density. **XL** loosely woven with the minimum insulation density. 

NEWPORT can cover any insulated wire in our handbook with metal overbraiding to protect against wear and abrasion. **Overbraiding** adds durability and electrical shielding for improved performance.
