Transit Cable and Wire

What makes Transit Cable different?

Transit cable is specially-designed to survive harsh elements and constant wear and tear while maintaining high levels of reliability. It is some of the strongest and most resilient cable available. Transit Cable will be put to the test under extreme temperatures and high levels of stress, so it must pass stringent critical requirements.

What are the general types of Transit Cable available?

Copper Products
Hybrid Multi-Core Cable - designed to meet special requirements
Fiber Optic Cable - rapidly becoming more accepted in the transit market

What kinds of critical requirements does Transit Cable have to meet?

While there are many types of requirements, some common ones are:

For Copper
AAR RP-585
AAR S-4210
NYCT Approval-TX
SMP 800-C
ICEA S-95-658
IEEE Flame Tests
BSS 7239
UL VW-1 Flame Test
For Fiber Optics
NES 711/713
Telcordia GR-20
IEC Flame/Safety Tests
NEC 770-51(b)/770-53(b)
NYCT Approval-TO

Transit cable insulation systems are often improved through radiation processing. What exactly is radiation processing?

Radiation processing uses a strong electron beam to cross-link the outer jacket to the insulation. Cross-linking stabilizes substances by bonding some of their molecular chains together. This allows for increased stability in high temperatures.
