Application

QINGZHOU QINGZHOU THHN or THWN-2 conductors are primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code. Voltage for all applications is 600 volts. QINGZHOU THHN conductors are designed to be used without application of pulling lubricant. Allowable temperatures are as follows:

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

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

• TWN75- Wet locations not to exceed 75° C

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

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

Construction

THHN or THWN-2 or MTW copper conductors are annealed (soft) copper strand, insulated with a tough

heat and moisture resistant poly vinyl chloride (PVC), over which a nylon or UL Recognized equal jacket is applied. Available in black, white, red, blue, purple, green, yellow, orange, brown and gray. Some colors are subject to economic order quantity.Marked sunlight resistant in sizes 2 AWG and larger. THWN sizes 14 -10 AWG. THWN-2 sizes 8 and larger.
