Nylon sheathed wire and cable has better electrical and physical properties than ordinary PVC insulated wire and cable: nylon sheathed wire and cable has good heat resistance, and has the characteristics of small weight loss under high temperature operation, which can improve the instantaneous thermal overload resistance of the wire. ability to slow or reduce the escape or migration of PVC components.
Nylon sheathed wire and cable has the characteristics of corrosion resistance, self-lubrication and oil resistance. Compared with the PVC insulated wire and cable of the same section, the nylon sheathed wire and cable has the characteristics of small outer diameter, light weight, low static friction coefficient and corrosion resistance, which can improve the safety and applicability in laying.
Nylon sheathed wire has a rated working voltage of 450/750V and is widely used in household appliances, aerospace systems, construction and lighting,. The long-term working temperature of the cable is 90°C or 75°C, the laying temperature is not lower than 0°C, and the bending radius should not be less than 4 times the outer diameter of the cable.
Type THHN/THWN conductors, in accordance with the National Electrical Code, installed through conduit, suitable for service, feeder and branch circuit wiring in
THHN cables are suitable for dry environments where the temperature does not exceed 90°C.
THWN cables are suitable for use in dry environments up to 90°C, in humid environments up to 75°C or in oil/coolant up to 75°C.
THWN – Category 2 cables are suitable for use in dry or wet environments up to 90°C and in oil/coolant up to 75°C.
MTW cables are suitable for use in wet environments, in oil/coolant with a temperature not exceeding 60°C, and in a dry environment with a temperature not exceeding 90°C (limited to the ampacity of 75°C conductors specified in NFPA 79).
In a dry environment where the conductor temperature does not exceed 105°C, the AWM type cable can be used as equipment wire and has a rated voltage of 600 volts.
