Product Description
Nylon Wire(THHN)
Product detail:
APPLICATION:
THHN wire is a very popular type of building wire used in all types of industrial, commercial and residential construction. This type of building wire is effective in damp and dry locations. THHN stands for Thermoplastic High Heat Nylon which is a description of the wire jacket and insulation components. The conductor comes in many strands for anything over 10 gauge in the stranded or solid conductor for gauges 14-10. THHN wire has an advantage as build wire because of its ability to handle up to 600 volts which covers most common appliances. The installation of THHN as building wire will fall within most building codes set out in the list of National Electrical Codes. This wire has a thermoplastic jacket releases toxic gases when burned. It cannot be used outside or buried due to its minimal protection. This is because this wire is used in building conditions where very little can hurt it. The jacketing protection is abrasion resistance but has little else in means of wire protection.
Cable construction
- Bare copper conductor, AWG-sizes as per given table below and ASTM B-3 and ASTM B-8
- Core insulation of PVC+Nylon-outer sheath
- Cores colour coded, colour identification see below
- Surface of jacket printed with markings:
* 14 to 1000 MCM THHN (stranded) - (size) AWG TYPE MTW OR THHN OR THWN 600 V OR GASOLINE AND OIL
