Abstract
A yellow green double color grounded flexible cable used in a communication power supply comprises an inner conductor (1). An isolating layer (2) is arranged out of the inner conductor (1). An insulating layer (3) is arranged out of the isolating layer (2). A sheath (4) is arranged out of the insulating layer (3). The flexible cable is characterized in that: a polyvinyl chloride color strip (5) is arranged out of the sheath (4). In the invention, a cold-resistant and flame-retardant polyvinyl chloride insulation material and a yellow green double-layer extrusion-color cold-resistant and flame-retardant polyvinyl chloride sheath material are used to substitute a polyvinyl chloride insulation material and a polyvinyl chloride sheath material used in an original product. The prepared cable possesses a low temperature resistance characteristic and is easy to be identified during usage and is easy to lay in a low temperature environment. A service life of the cable in the low temperature environment can reach more than 25 years. The cable has many other advantages.

Technical field
The invention belongs to the power cable category, mainly is that a kind of communication power supply is used the cold-resistant flame-retardant flexible electric cable with yellow and green ground connection sign, and the present invention belongs to communication power supply in fact and uses flexible electric power cable, and the rated operational voltage of cable is: 600/1000V.The present invention mainly as plateau communication bureau (station), cold-resistant iron tower of having relatively high expectations, comparatively cold power supplys such as area fail, the earth cable of distribution system.
Background technology
At present, the standard that the communication power supply that domestic enterprise manufactures is carried out with flame-retardant refractory flexible electric cable is YD/T1173-2001, does not stipulate earth cable color and specification requirement in the standard.At present, most of manufacturer adopts black pvc insulation PVC sheath flexible cable as earth connection on the market.
The specific (special) requirements that this existing cable color and performance can not satisfy the user: 1, be unfavorable for distinguishing the cable connection mode.Because of balck cable possibly use as zero line or live wire, and yellow and green necessarily uses as ground connection, very easily distinguishes.2, be difficult for laying installation.Because of common cable polyvinyl chloride insulation and sheath material cold-resistant (laying ambient temperature be-15～+ 60 ℃), insulating barrier and restrictive coating are harder in the low temperature environment below-20 ℃, not flexible lay and when crooked very easily breakage ftracture.3, reduction also there is the service life of cable.Because of common cable PVC insulation and sheath material mechanical and physical performance and low temperature cracking resistance, shock test in the low temperature environment below-20 ℃ all can exceed the requirement of YD/T 1173-2001 canonical parameter; Aging and the crack velocity of cable can be accelerated, and the useful life of cable can be much smaller than 20 years of normal use.
Summary of the invention
The present invention seeks in order to overcome above-mentioned defective, provide a kind of communication power supply with having the cold-resistant flame-retardant flexible electric cable of yellow and green ground connection sign.The invention solves to be beneficial to and distinguish the cable connection mode, be easy to the technical problem of laying, increasing the service life.
Technical scheme of the present invention is:
The present invention adopts cold-resistant flame-proof polyvinyl chloride Insulation Material, yellowish green bilayer to extrude the cold-resistant flame-proof polyvinyl chloride protective cover material of color, substitutes the polyvinyl chloride insulation material and the pvc sheathing compound that use in the original product.
A kind of communication power supply comprises inner wire with yellow and green ground connection flexible cable, and inner wire is provided with separator outward, and separator is provided with insulating barrier outward, and insulating barrier is provided with sheath outward, and said sheath is provided with the polyvinyl chloride vitta outward.
