Development of flame retardant and anti-pollution (AP) electric cable

Varies means are in use to prevent the spread of cable fire. But little attention has been paid to the generation of smoke, corrosive gas, and toxic gas from burning cables. In Europe control on gas-producing cables is widespread, and Japan is beginning to be influenced by it. The authors report their development of what is called ''anti-pollution flame-retardant cable'' which produces no metal-corroding and highly toxic halogenides and only very little smoke. The AP cable can be designed in varied constructions according to the applications for which it is used. It is therefore usable for power transmission, communications, ships, vehicles, nuclear power facilities, etc. (author)
