Nylon Jacket 2.5mm 4mm 10mm 16mm Single Core Electrical Cable Wires Copper

Product Description

Product Description

CONSTRUCTION

THHN/THWN conductors are made with soft drawn copper. Sizes 14 through 4/0 AWG use a combination-unilay stranding while 250 kcmil and larger sizes use a compressed copper stranding.

The wire is covered with a tough heat and moisture resistant PVC insulation with an overall nylon jacket.

Available in black, white, red, blue, purple, green, yellow, orange, brown, and gray. Some colors are subject to economic order quantity.

APPLICATION

General purpose wiring in accordance with the National Electrical Code, maximum conductor temperature of 90°C in dry locations and 75°C in wet locations, 600 volts, for installation in conduit or other recognized raceway. Also used for wiring of machine tools (stranded), appliances, and control circuits not exceeding 600 volts.

These conductors have multiple ratings. Depending upon the product application, allowable temperatures are as follows:

• THHN or T90 Nylon- Dry locations not to exceed 90℃

• THWN-2- Wet or dry locations not to exceed 90° C or locations not to exceed 75℃ when exposed to oil

• THWN- Wet locations not to exceed 75℃ or dry locations not to exceed 90° C or locations not to exceed 75℃ when exposed to oil

• TWN75- Wet locations not to exceed 75℃

• MTW- Wet locations or when exposed to oil at temperatures not to exceed 60° C or dry locations not to exceed 90℃ (with ampacity limited to that for 75℃ conductor temperature per NFPA 79)

• AWM- Dry locations not to exceed 105℃ only when rated and used as appliance wiring material

Voltage Test

Each drum of finished cable should withstand power frequency voltage 3.5kV for 5 minutes,the insulation is not breakdown.
Service conditions and operation parameters of Cable:
The cable is applied to fixed installation for rated voltage 0.6/1kV of power transportation and distribution line.
Max. rated temperature of conductor. nominal operating 90ºC
Short circuit: max. for 5 sec.250ºC
The cable can be laid without drop restriction, and the environment temperature shall not be lower than 0ºC.
