Category 7 (Cat 7) LAN Cables for High-speed Communications

Category 7 LAN Cables for High-speed Communications

DESCRIPTION

Cables for use in rolling stock must satisfy the fire safety requirements as specified in the applicable fire safety standards, and must pass a set of fire tests that measure flame-resistance, smoke generation, and toxicity. Utilizing our exclusive fire safety design technologies for rolling stock electrical wiring that Hitachi Metals has developed over the years, we have now launched CO-IREE-SB C7E(X), a rolling stock Cat.7 LAN cable. The unique cable structure and our exclusive highly flame retardant halogen-free outer sheath enabled us to realize a product that can simultaneously deliver both high-performance electrical characteristics and European railway fire safety.

Features of CO-IREE-SB C7E(X):

  1. Insulator
    • Micro foam technology*3 and multilayer extrusion technology successfully reduced dielectric properties and use of flammable insulation materials.
  2. Shielding tape
    • Our unique taping method shields electromagnetic interference, ensuring the electrical characteristics and high bandwidth of up to 600 MHz required by a Cat.7 LAN cable.
  3. Outer sheath material
    • Adoption of a highly flame-retardant halogen-free material exclusively developed by Hitachi Metals in the cable outer sheath satisfies fire safety standards, including the low smoke generation and low toxicity required by EN45545-2.

The introduction of CO-IREE-SB C7E(X) to our product lineup will help Hitachi Metals to respond to customer demand in Europe and Asia for higher performance in cables and wiring for use in rolling stock.

Proterial will continue to focus on the development of new materials and on contributing to the technological advancement of train vehicles through our solution technologies that target the range of challenges faced by our customers.
