26、ation Section 1 GENERAL 1.1 SCOPE This standards publication covers specific requirements for FEP (Fluorinated Ethylene Propylene) insulated solid and stranded wire, designed for the internal wiring of high reliability electrical and electronic equipment. This standards publication addresses 250 vol

27、t (type KT), 600 volt (type K), and 1000 volt (type KK) wire and permits continuous conductor temperature ratings of -65 g113C to + 200 g113C with silver-coated or nickel-coated conductors and -65 g113C to +150 g113C with tin-coated conductors. These types of hook-up wire are used when the following

28、 requirements are called for: g120 High temperature resistance; g120 low temperature resistance; g120 low dielectric constant; g120 resistance to cleaning solutions or a variety of chemicals that may come in contact with either the wire or the equipment; and, g120 good flexibility and flex life when

29、 stranded conductors are used. 1.2 REFERENCED STANDARDS AND SPECIFICATIONS American Society for Quality Control 611 E.

It is considered suitable for use up to a maximum of 250 volts rms (roo

35、t mean square) and/or for high frequency circuitry. Wires having KT thin wall insulation are relatively fragile and can be damaged. They should not be used where a mechanical stress or an abrasive environment may exist. 1.3.2 Type K Type K is intended for high temperature applications and is conside

36、red suitable for use at a maximum of 600 volts rms and/or for high frequency circuitry. 1.3.3 Type KK Type KK is intended for high temperature applications and is considered suitable for use at a maximum of 1000 volts rms and/or for high frequency circuitry.
