25、This standards publication covers specific requirements for PTFE (polytetrafluoroethylene) insulated solid and stranded wire designed for the internal wiring of high reliability electrical and electronic equipment. This Standards Publication addresses 250 volt (Type ET), 600 volt (Type E) and 1000 v
26、olt (Type EE) wire and permits continuous conductor temperature ratings of -65g113 C to +200g113 C with silver-coated conductors and -65g113 C to +260g113 C with nickel-coated conductors. These types of hook-up wire are used when the following properties are called for: g120 High temperature resista
27、nce g120 Low temperature resistance g120 Low dielectric constant g120 Solder iron resistance g120 Resistance to cleaning solutions or a variety of chemicals that may come in contact with either the wire or the equipment g120 Good flexibility and flex life when stranded conductors are used 1.2 REFERE

33、3.0 kHz Insulation Continuity Proof Testing of Hook Up Wire 1.3 RECOMMENDED USES OF WIRE TYPES 1.3.1 Type ET Type ET wire is intended for use in low voltage, high temperature applications. It is considered suitable for use up to a maximum of 250 volts RMS (root mean square) and/or for high frequency
34、 circuitry. Wires having ET thin wall insulation are relatively fragile and can be damaged. They should not be used where mechanical stress or an abrasive environment may exist. 1.3.2 Type E Type E is intended for high temperature applications and is considered suitable for use at a maximum of 600 v
35、olts RMS and/or for high frequency circuitry. 1.3.3 Type EE Type EE 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.
