TOKYO--(Business Wire)--
Hitachi Cable (TOKYO:5812) is announcing a new lineup of halogen-free heat
resistant LAN cables for rolling stock as a part of our related product lineup.
The products in this new lineup are highly heat resistant and can withstand
temperatures of 90 deg C and satisfy the fire safety standards required in the
EN (note 1). 

As measures to reduce CO2 emissions are being reinforced to mitigate global
climate change in the recent years, railroad transportation is receiving
attention for its low energy consumption and low CO2 emissions per traffic
volume, resulting in the reduction of global environmental load. Demand for
wires and cables for rolling stock is increasing in overseas markets, including
rapid railroad projects being implemented mainly in Europe and Asia. Demand for
high-speed and large-capacity information and telecommunication services such as
Internet connections and video sharing in rolling stock is spreading along with
the implementation of rapid railroad projects. LAN cables specifically designed
for Ethernet (note 2) connections in rolling stock are being used as
communication lines inside rolling stock. Furthermore, Ethernet is gaining
acceptance towards advanced features of railroad operation and control systems,
and demand for LAN cables for Ethernet installation with cables for rolling
stock vehicle control is also increasing. 

In response to such needs, Hitachi Cable is introducing a product lineup of
halogen-free heat resistant LAN cables for rolling stock with high heat
resistance required for use in rolling stock and in Enhanced Category 5 (note 3)
which satisfies high fire safety standards required in the EN.
The halogen-free heat resistant LAN cables for rolling stock in this new lineup
use special flame-resistant cross-linked polyethylene as sheaths. Hitachi Cable
developed this special flame-resistant cross-linked polyethylene using polymer
compounding technologies that the company has accumulated through the
development of various types of wires and cables and realized high heat
resistance up to temperatures of 90 deg C, which is much higher than the heat
resistance of conventional products with resistance generally at temperatures of
60 deg C. The use of this flame-resistant cross-linked polyethylene developed
for this lineup ensures a high level of fire safety required for wires and
cables for rolling stock in the EN, which means high level of fire resistance,
low smoke emission, and low toxicity. Furthermore, reducing the sheath thickness
as much as possible while retaining a high level of fire resistance made the
products resistant to thermal expansion and shrinkage and retain electric
performance which satisfies Enhanced Category 5 under a high temperature
environment of 90 deg C. 

Hitachi Cable is committed to expanding the sales of wires and cables for
rolling stock by conducting development to further improve the performance of
products such as heat resistant LAN cables and enhancing its product lineup.
