What makes Transit Cable different from other cables?
Transit cable is specially-designed to survive harsh elements and constant use 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 types of Transit Cable are available?
The three most common types of transit cable are copper products, hybrid multi-core cables, and fiber optic cables. Hybrid multi-core cables are designed to meet special requirements, and fiber optic cables are rapidly becoming used more and more in the transit industry.
Allied Wire and Cable also carries Polyrad® Cable. This type of rapid transit cable is especially known for its wide temperature range, durability, and resistance to environmental hazards.

What is radiation processing? What does it do for Transit Cables?
Transit cable insulation systems are often improved through radiation processing. Radiation processing uses a strong electron beam to cross-link the outer jacket to the insulation. Cross-linking stabilizes substances by bonding their molecular chains together. This allows for increased stability in high temperatures.
