THHN-THWN -THW-TW(Nylon sheathed PVC construction wire) meets or exceeds the requirements of ASTM, IEC, DIN, BS, AS, CSA, NFC, SS and other international standards. In addition, we accept OEM services to meet your special requirements.
1.THHN/THWN/THW/TW cables are intended for general purpose applications as defined in the National Electrical Code (NEC). The THHN-WN -2 cable allows for new construction or rewiring in 60 volt applications. A THHN or THWN type application is required.
A. THHN wire: single or stranded wire with flame retardant and heat resistant thermoplastic insulation, covered with extruded nylon or similar material. Wire rated temperature is 90℃, dry only. THHN cable can also be used for machine tools, control circuits or some electrical wiring.
B. THWN wire: it is a single conductor with flame retardant, moisture proof and heat resistant thermoplastic insulation, the outer sheath is extruded nylon or similar material. Wire rated at 75℃ wet or dry. THWN cables are commonly used for installation in conduits, machine tools, control circuits, or other general purpose wiring.
C. HTW Wire -- indicates a single conductor with flame retardant, moisture proof, heat resistant thermoplastic insulation. Wire rated at 75℃ wet or dry. THW cables and wires are commonly used for building wiring, feeders and branches, and internal secondary industrial power distribution.
D. Twwire -- represents a single conductor with flame retardant, moisture resistant thermoplastic insulation. Wire rated at 60℃ wet or dry. TW cables and wires are generally used for building wiring, feeders and branches, and internal secondary industrial distribution.
2, suitable for wet or dry, temperature not more than 90℃ or not more than 75℃ in the oil or coolant. Applications requiring MTW conductors are suitable for dry conditions up to 90 ° C or damp conditions up to 60 ° C or exposure to oil or coolant. Applications requiring AWM conductors are suitable for dry environments where the temperature does not exceed 105℃.
1) Nylon sheath PVC wire, easy to pull. Vw-1 rated at 14 AWG-8 AWG. All sizes are rated for gasoline and oil resistance II.
2) Sheath: nylon sheath is used to prevent the abrasion and scratch of PVC insulation material when the pipe is pierced. It is also resistant to oil, gasoline and chemicals.
Insulation: POLYvinyl chloride (PVC) with secondary nylon sheath
Conductor: annealed solid or stranded copper wire (copper or CCA)
Voltage level :600 V.
The THHN or THWN or MTW line (also called AWM) meets or exceeds the requirements of all applicable ASTM specifications,UL standard 83,UL Standard 1063 (MTW), Federal Specification A-A-59544 and the National Electrical Code.
