The thin-walled high pressure resisting double-layer insulated cable has the following advantages of good binding effect between the inner insulating layer and the conductor as well as between the inner insulating layer and the outer insulating layer; as the inner insulating layer and the outer insulating layer are respectively acted by cross-linked polyolefin and kynoar, the insulated cable is excellent in resistance to chemical corrosion resistance, and has heat resistance, oxidation resistance, climate resistance and ultraviolet radiation resistance; and by adopting the provided technology, the thicknesses of the inner insulating layer and the outer insulating layer are reduced, thereby the weight is reduced and the wiring space is saved.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, is specifically related to the high pressure resistant double-insulated cable of a kind of thin-walled, is applicable to rail traffic vehicles and motor
Background technology
Take the subway of track traffic category as example, because railcar has strict restriction at aspects such as space and deadweights, the vehicle electric control circuit is much more than common railway in addition, institute takes up space for the weight that alleviates the bunchy electric wire and when saving the laying wires cable, therefore generally adopts high-performance thinwalled insulation cable.Again, fast development along with car industry and electric manufacturing, electron controls technology is commonly used, add people more and more higher to the requirements such as fail safe, comfortableness, economy and discharging spatter property (being the feature of environmental protection) of automobile, electrical configurations function on the automobile is increasing, correspondingly, the cable that connects electrical configurations also increases.
With regard to automobile, according to related data, China's to 2010 year auto output has reached 1,800 ten thousand, and a high-grade car is 2500m with wire rod on average.Therefore how to make the electric wire that is applied to track traffic and automobile and motor the oil resistant burn into wear-resistant and high pressure resistant with reduce external diameter and save between the wiring between find the rational balance point to become the technical problem of the common concern of cable developing department and production firm.
Usually adopt in the prior art soft PVC as inner insulating layer and with crosslinked PVC as external insulation layer, the shortcoming of this double-insulated cable is that mutual capacitance and decay are large.If yet adopt high density polyethylene (HDPE) as inner insulating layer and adopt the semihard flame-proof PVC as external insulation layer, can occur so being difficult between the inside and outside insulating barrier boning, the problem of interface roughness and external diameter fluctuation.
In view of this, be necessary it is improved, the applicant has done useful design for this reason, and technical scheme described below is based on producing under this prerequisite
Summary of the invention
Task of the present utility model be to provide a kind of help significantly to improve between the external insulation layer each other in conjunction with effect, be conducive to promote with conductor in conjunction with effect, be of value to and ensure desirable chemical resistance and the high pressure resistant double-insulated cable of thin-walled of high temperature resistant and high pressure resistant effect.
Task of the present utility model is finished like this, the high pressure resistant double-insulated cable of a kind of thin-walled, comprise conductor and be combined in successively conductor outer inner insulating layer and external insulation layer, described conductor is that diameter is the tinned copper wire of 0.1-0.3 ㎜, described inner insulating layer is cross-linked polyolefin, and described external insulation layer is Kynoar.
The thickness of inside and outside insulating barrier described in the utility model is equal to each other.
The thickness of the described external insulation layer of Thickness Ratio of inner insulating layer described in the utility model is thick.
The thin thickness of the described external insulation layer of Thickness Ratio of inner insulating layer described in the utility model.
The thickness of inner insulating layer described in the utility model is 0.05-0.15 ㎜, and the thickness of described external insulation layer is 0.05-0.15 ㎜.
The technical scheme that the utility model provides has good in effect between inner insulating layer and the conductor and between the inside and outside insulating barrier, because inside and outside insulating barrier is filled the post of by cross-linked polyolefin and Kynoar respectively, therefore have excellent chemical resistance, high temperature resistant, resistance to oxidation and wait, the strong point such as UV resistant radiation, and can reduce the thickness of inside and outside insulating barrier and use weight reduction and save wiring space with respect to prior art.
