Abstract
The invention discloses a special thin-wall control flexible cable for fan motors, comprising a plurality of insulated core wires and a wrapping layer coating the insulated core wires. The wrapping layer is coated with a heat-resistant, irradiation-free and flame-retardant insulated polyvinyl chloride sheath layer. Each insulated core wire is composed of a conductor and an insulating layer coating the conductor. The thickness of the insulating layers is reduced by 1/3. According to the special thin-wall control flexible cable for fan motors provided by the invention, although the material consumption of the insulating layers is reduced greatly, the insulation performance at high temperature is not significantly decreased, and the cable still meets the basic requirements of fan motors for the insulating performance of cables in high-temperature environments.
Description
Technical field
The present invention relates to data cable, be specifically related to the special control flexible cable of a kind of thin wall type blower motor.
Background technology
The blower fan of the equipment such as central air-conditioning, workshop ventilation, HVAC uses for a long time in high temperature environments, under the cable of its blower motor is also in hot environment certainly.The sheath material of current blower motor cable is made up of polyvinyl chloride usually, it belongs to the not high material of heatproof, can the high temperature of resistance to 105 DEG C, when cable is in operation the too high or load height of electric current, be easy to require that producing colloidal sol ftractures and burn because temperature resistant grade does not reach, the a large amount of toxic smog of easy generation, to the environment of surrounding, brings certain potential safety hazard to production and life.
Applicant replaces traditional pvc sheath layer by adopting heat-resisting irradiation fire retardant insulating pvc sheath layer of exempting from, not only environmental protection flame retardant, also reach the job requirement of Long-Time Service under 125 DEG C of hot environments, improve the security performance under blower motor hot environment.But owing to requiring higher to the insulating properties under cable core hot environment, usually adopt thicker insulating barrier to ensure the insulating properties of cable.
Summary of the invention
In view of this, the object of the present invention is to provide the special control flexible cable of a kind of thin wall type blower motor, this cable not only has high pliability and oil resistant, fire-retardant, high and low temperature resistance, and drastically reduce the area the consumption of insulating layer material.
