High voltage level of the high-voltage motors, usually 6KV and 10KV motor main power wiring inside the junction box cable insulation is very important, motor connection cable is divided into two parts, part of the motor stator outlet cable, another part of the motor is running power supply cable. The national standard GB14711-2006 "Safety requirements of small and medium-sized rotary motor provides: a rated voltage of the the 6KV motor, the different live parts of the terminal box minimum clearance of 50mm, minimum creepage distance of 80mm; rated voltage of 10KV motor, wiring box live parts minimum clearance of 90mm, minimum creepage distance of 160mm. In order to ensure the electrical junction box connection cable clearances and minimum creepage distance to meet the requirements of the national standard, the majority of domestic high-voltage motors manufacturer, insulation of insulated terminals. Welding the ends of the cable outlet of the motor stator terminal bolts, wiring bolt material is copper, wiring bolt set within the insulated terminals, insulated terminals materials for the ceramic or DMC. The motor stator outlet cable and power supply cable connected with bolts. This structure in the two sections of cable bolted, power supply cable prone to skew, two sections of exposed energized minimum clearances and minimum creepage distance is difficult to guarantee the charged body discharge, short-circuit the motor burned. This wiring, welding junction bolt, low efficiency.

    We are using the technology program: in the junction box installed at the bottom of an epoxy glass cloth laminated sheet 3240 material outlet plate, drill hole diameter imprevement of diameter 30 on the outlet panel according to the number of outgoing cables, the stator outlet cable from the three-hole wear out the cable jacket rubber seal materials, plugged outlet hole gap, while also protecting the stator outlet cable. The lower end of the outlet plate drilled two diameters ?4 mounting holes for mounting clamp, clamp material is glass cloth board 3240 clamp for fixing the three stator outlet cable. Each stator outlet end of the cable lugs, lugs and cable by cold pressing process connections. The power cable to the motor power supply, the power cable from the cable outlet of the stator bolted connection with high voltage insulation tape bandage. The motor terminal length can be adjusted to avoid the drawbacks of the length of the supply cable inappropriate.

    The beneficial effects: all the live cable insulation, no bare live off the motor energized cables discharge phenomenon, to ensure the safe operation of the motor. Easy installation, high efficiency, fewer parts.

    We invented this new type of high-voltage motors outlet method has been applied for national patents.
