Product Overview

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...
