Description

Flame-retardant heat-insulation motor connecting wire

Technical Field

The utility model belongs to motor lead-out wire field, more specifically say, relate to a fire-retardant thermal-insulated motor connecting wire.

Background

The motor connecting wire is a lead wire connected with the connection between the motor and an external power supply and plays a role in connecting the power supply during the work of the motor. The motor lead-out wires are typically mounted inside the device.

In view of this, the motor connecting wire has strict requirements on insulation and conduction of the motor connecting wire, and has certain requirements on flame retardant and heat insulation performance, because the interior of the device is in a working state for a long time, the temperature is high, the possibility of spontaneous combustion is greatly improved, higher requirements on the flame retardant performance of the connecting wire are provided, and the existing connecting wire cannot meet the flame retardant requirements.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a fire-retardant thermal-insulated motor connecting wire, reasonable in design, the line is dragged to inside tensile has good tensile to drag the performance, has sufficient pliability, and the motor connecting wire still has good insulation, fire-retardant, thermal-insulated and antioxidant property moreover, satisfies being connected of motor and power in the equipment, and the overall stability can be good, and long service life begins to promote.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a fire-retardant heat-insulating motor connecting wire which characterized in that: the anti-pulling device comprises an anti-pulling line arranged in the middle, wherein an insulating filling material is wrapped on the outer surface of the anti-pulling line, and a plurality of wires are laid in the insulating filling material; the outer surface of the insulating filling material is sequentially provided with a mica tape layer, a polyurethane belting layer, a low-smoke halogen-free butyronitrile insulating layer and an aluminum foil layer from inside to outside, the outer surface of the aluminum foil layer is wrapped with a polygonal shell, and the polygonal shell is a shell made of a PVC material through an injection molding process.

As an optimized technical scheme, the tensile wire is made by stranding a plurality of glass fiber tensile wires.

As an optimized technical scheme, the insulating filling material is a filling rope body made of a PP material.

As an optimized technical scheme, the polygonal shell is pentagonal or hexagonal.

As an optimized technical scheme, the outer surface of the polygonal outer shell is wrapped with an outer sheath made of polyurethane.

Since the technical scheme is used, compare with prior art, the utility model relates to a rationally, the line is dragged to inside tensile has good tensile and pulls the performance, has sufficient pliability, and the motor connecting wire still has good insulating, fire-retardant, thermal-insulated and antioxidant property moreover, satisfies being connected of motor and power in the equipment, and the overall stability can be good, and long service life begins to promote.

The present invention will be further explained with reference to the drawings and examples.
