Abstract
A cold resistant cable relates to the technical field of cable structures and comprises a silicon rubber sheath layer, the silicon rubber sheath layer is sequentially provided with an armor layer, a PVC inner protective layer, a main shield layer and a tape from outside in, three pair individual-shield cable core sets and three single shield wires respectively disposed between and outside every two adjacent cable cores are arranged inside the tape, wire cores are arranged inside each individual-shield cable core, each wire core includes a conductor and a silicon rubber insulated layer outside the conductor, a wrapping tape, a shield layer and a PVC sheath are sequentially arranged outside the wire cores, and the single shield wire includes a conductor, and a silicon rubber insulated layer, a shield layer and a PVC sheath sequentially arranged outside the conductor. The cold resistant cable has the advantages of tensile resistance, high interference resistance, cold resistance and high safety factor.
Description
Technical field
The utility model relates to the technical field of the construction of cable.
Background technology
The applicability of cable and fail safe can both normally transmit electric energy for using at special occasions, accurately transmission signals is very important, severe cold frost region particularly, harsh climate changes, often do not reach instructions for use because of the cable cold tolerance, break and open circuit, and cause the transmission signals disorder, make equipment produce misoperation, cause casualties and property badly damaged.
The utility model content
The purpose of this utility model is to design a kind of tension, anti-strong jamming, cold-resistant, comprehensive practical cold resistant cable that coefficient of safety is high.
The purpose of this utility model is achieved in that the utility model comprises the silicone rubber jacket layer, establish armour, PVC sheath, total screen and band in the silicone rubber jacket course successively, three shielding single lines outside establishing three groups of pair twist split screen cable cores in the band and being arranged between the two adjacent cable cores; Divide in the shielding cable core and establish core, core comprises conductor and is arranged on the outer silicone rubber insulation layer of conductor that core is established pair twist twining package tape, screen and PVC sheath outward successively; The shielding single line comprises conductor and is successively set on conductor outer silicone rubber insulation layer, screen and PVC sheath.
Establish three groups of cores in the described branch shielding cable core.
Described armour is the zinc-coated wire armour.
Described total screen is that copper mesh weaves total screen, and screen is the copper mesh woven shield.
The utlity model has tension, anti-strong jamming, performance such as cold-resistant, the coefficient of safety height is specially adapted to the severe cold frost region and has the freezing occasion that requires to use.Cable insulation and sheath adopt fire-retardant Halogen silastic material, and fire-retardant, corrosion resistant, softness, cold tolerance are good; Adopt shielding to add the composite construction of slim PVC sheath, antijamming capability is strong; Adopt the zinc-coated wire armouring, increase the tensile strength of cable greatly; Thereby effectively guaranteed accuracy, fail safe and the applicability of cable in the transmission of special occasions signal, Data Detection.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model
1,6 is that oxygen-free copper conductor, 2,7 is that silicone rubber insulation layer, 3 is that pair twist twining package tape, 4,8 is that copper mesh woven shield, 5,9 is that slim PVC sheath, 10 is that band, 11 is that PVC sheath, 13 is that zinc-coated wire armour, 14 is the silicone rubber jacket layer for copper mesh weaves total screen, 12 in the picture in picture.
Embodiment:
The utility model comprises silicone rubber jacket layer 14, silicone rubber jacket layer 14 inwardly successively zinc-coated wire establish armour 13, PVC sheath 12, copper mesh and weave total screen 11 and band 10, establish three groups of pair twist split screen cable cores in the band 10 and be arranged on three shielding single lines in the outside between the two adjacent cable cores; Divide in the shielding cable core and establish three cores, every core comprises oxygen-free copper conductor 1 and is arranged on oxygen-free copper conductor 1 outer 2, three cores of silicone rubber insulation layer establishes pair twist twining package tape 3, copper mesh woven shield 4 and slim PVC sheath 5 outward successively; The shielding single line comprises oxygen-free copper conductor 6 and is successively set on oxygen-free copper conductor 6 silicone rubber insulation layer 7, copper mesh woven shield 8 and slim PVC sheath 9 outward.
