A new fire-resistant cross-linked polyvinyl chloride is replacing textile-reinforced wire insulations in Bell System central offices. Cross-linking is done by electron beam radiation in air, rather than in a vacuum. Tests of the new insulation were conducted on 22-gage tinned wire. The close cooperation between Bell Telephone Labs and Western Electric in developing the new insulation is stressed.
