Rosslyn, VA, October 30, 2007 -- The National Electrical Manufacturers Association (NEMA) has published NEMA HP 6-2007 Electrical and Electronic Silicone and Silicone-Braided Insulated Hook-Up Wire Types S (600 V), ZHS (600 V), SS (1000 V), ZHSS (1000 V), and SSB Braided (1000 V).
HP 6-2007 was developed by the NEMA High Performance Wire and Cable Section as a non-government standard for replacement of MIL-W-16878 silicone rubber-insulated wire slash sheets (/7, /8, /29 through /32). It covers requirements for silicone rubber-insulated stranded wire that is used in the internal wiring of high-reliability electrical and electronic equipment. It addresses 600 V (types S and ZHS) and 1,000 V (types SS, ZHSS, and SSB) wire. The standard permits continuous conductor temperature ratings of -55ºC to +150ºC (tin-copper) or +200ºC (silver-copper) with either tin-coated or silver-coated conductors.
The specified types of hook-up wire are designed for high-temperature resistance; low-temperature resistance; good flexibility and flex life; solder-iron resistance for easier solder terminations without potential damage; and types ZHS and ZHSS, which are used for applications requiring low-smoke and zero-halogen requirements.
