The utility model content
The purpose of this utility model is design, produces a kind of novel construction of cable, and the mine that is specially adapted to all kinds of operational environment complexity is done signal transmission usefulness.
For achieving the above object, technical solutions of the utility model are as follows:
The utility model provides a kind of mining signal cable, comprise that the outer extruded insulation layer of conductor consists of heart yearn, after selecting two or two above heart yearns stranded, set gradually group drainage thread, group copper strip shielding layer, group separator, group woven shield formation group cable core, the many total cable cores of the group stranded formation of cable core, be provided with the packed layer that blocks water in described total cable core gap, outside described total cable core, set gradually separator, drainage thread, copper strip shielding layer, inner sheath, flame retardant coating, woven shield, water blocking layer, oversheath.Mining signal cable of the present utility model has the characteristic of protection against the tide, waterproof, fire-resistant, anti-electromagnetic wave, and the mine that is specially adapted to all kinds of operational environment complexity is done the signal transmission and used.
Described conductor, group drainage thread and drainage thread can be selected sub-thread tin plated wire or multiply tinned copper wire to twist again and form, increase the anti-corrosive properties of conductor in wet environment.
Described insulating barrier, inner sheath adopt polyethylene to extrude and form, and have good resistance to low temperature, and chemical stability is good, and the erosion of the most of soda acids of ability is insoluble to common solvent under the normal temperature, and water absorption is little, and electrical insulation capability is good.
Described group of copper strip shielding layer, copper strip shielding layer adopt conducting surface wrapped and drainage thread conducting inwardly, form independently 100% screen that covers, and can play uniform electric field, prevent from reaching external signal to the interference of cable inside between the inner group of the cable cable core.
Described group of separator, separator adopt wrapped the forming of high temperature resistance polyester band, compound copper-plastics band and woven shield are done the insulation processing, thereby form independently double shield layer.
Described group of woven shield, woven shield adopt the tinned copper wire braiding to form, and improve the anti-oxidation and anti-corrosive properties of woven shield.
The described packed layer that blocks water is filled by waterproofing rope and is formed, and prevents that the globule from vertically invading cable.
Described flame retardant coating adopts the mica tape stacked package to form, so that cable has good fire protecting performance.
Described water blocking layer adopts the single face insulation waterstop is wrapped and forms, and prevents that the globule from radially invading cable.
Described oversheath can adopt flame-proof polyvinyl chloride, low-smoke halogen-free polyolefin, flame-retardant thermoplastic elastomer, any material of flame-proof thermoplastic polyurethane to extrude and form.
The utility model compared with prior art has following advantage:
1, the group cable core adopts double-layer shielding structure, comprises that drainage thread adds screen and the group woven shield that wrapped formation 100% shielding of compound copper-plastics band covers and can reach 90% shielding coverage effect, so that the signal between the group cable core of cable inside does not interfere with each other.
2, total cable core arranges separately respectively independently copper strip shielding layer and woven shield outward, forms double-deck external shield, both can prevent the interference of external electromagnetic waves, and internal signal disturbs the signal of external equipment when also preventing the cable operation.
3, block water packed layer, water blocking layer, inner sheath can effectively prevent vertically and infiltration radially.
4, flame retardant coating adopts the mica tape stacked package to form, and can prolong the operating time of important instrument equipment in accident.
5, oversheath adopts flame-proof polyvinyl chloride, low-smoke halogen-free polyolefin, flame-retardant thermoplastic elastomer, any material of flame-proof thermoplastic polyurethane to extrude and form, so that mining signal cable can satisfy various complex work environment.
