HW291 HL Listed CIR® Instrumentation Cable Individually Shielded Pairs + Ground 0.6/1kV 90° Gexol® Insulation

Product Description: 

This product pairs the flexible, crush-resistant integrity of CIR® cables with the virtually impenetrable protection of Gexol® polyolefin insulation.  The combination equates to an extremely resilient, long lasting assembly that can tolerate some of the harshest abuse Mother Nature is capable of dishing out.  The construction of this product consists of tinned copper conductors that are formed into pairs or triads and wrapped in Gexol® insulation.  A polyester-backed foil tape for shielding then covers the insulation.  The tinned copper CIR® conductors are a preferred alternative to Type MC due to their smaller bend radius.  CIR® conductors also offer less tray fill with a smaller overall cable radius.  The entire assembly is jacketed with a black thermoset compound that is flame retardant and defends the conductors against oil, sunlight, corrosive chemicals, and abrasion.

Applications:

Underwriters Laboratories rates this product as approved for use in hazardous locations as well as for use on marine vessels or offshore structures.  The cable’s ability to tolerate heavy impact without being crushed makes it the perfect cable to handle tasks at sea.  The outer jacket is composed of a thermoset compound that is impervious to the corrosive effects of salt water and oil.  Installation within cable tray is recommended for this cable, however the cable meets UL ratings for TC-ER and TC-ER-HL, deeming the product safe to make exposed runs while still functioning safely.

Specifications:

• In accordance with specifications set forth by Underwriters Laboratories, this cable passes the IEEE 1202 flame test. 
• This product meets or exceeds standard 1277 and 2225.  These standards require the conductors to meet necessary criteria so they can be approved for use in hazardous locations. 
• This cable is rated TC-ER by Underwriters Laboratories.  This classification deems the cable safe for installation in cable tray as well as without cable tray.
• This cable is rated TC-ER-HL by Underwriters Laboratories.  In accordance with 336.10(7) and 505.15(B)(1)(i) and as permitted in 501.10(A)(2) of the NEC, the cable is safe for use in exposed runs between utilization equipment and a cable tray.  It can also be used where the cable is protected against physical damage using channel, struts, or angles.

Construction:

• Conductors

-                The conductors in this cable are CIR® flexible stranded, soft annealed tinned copper.  The tin-plating on the copper increases the lifespan of the conductive properties of the cable by up to ten times that of a bare copper conductor.

• Ground Wire

-                The assembly includes a bare copper ground conductor.  The ground conductor ensures steady conductivity for the life of the cable. 

• Insulation

-                Each phase conductor is individually insulated with Gexol® polyolefin insulation.  The polyolefin insulation is flame retardant in accordance with UL standards.

• Shielding

-           Each triad or pair is wrapped in a polyester-backed foil tape.  The foil tape provides additional shielding to the conductors, then the entire assembly is wrapped in foil.  

• Outer Jacket
