Abstract
The utility model disclose an antistatic high-performance mine signal transmission cable, and relates to the technical field of cable manufacture. The antistatic high-performance mine signal transmission cable comprises a cable core. The outer side of the cable core is provided with a cabling wrapping layer, an aluminium-plastic composite tape main shielding layer, a low-smoke halogen-free fire-retardant liner layer, a longitudinally-wrapped stainless steel corrugated tape armor layer and an antistatic fire-retardant PVC outer sheath layer successively. A first current lead wire is arranged in the inside of the aluminium-plastic composite tape main shielding layer. A fire-retardant filling layer is arranged between the cable core and the cabling wrapping layer. The cable core comprises a plurality of groups of wire cores. Each wire core comprises insulated conductors which are twisted into pairs. The outer side of the insulated conductors which are twisted into pairs is provided with an aluminium-plastic composite tape branch shielding layer and a polyester film wrapping layer successively. A second current lead wire is arranged in the inside of the aluminium-plastic composite tape branch shielding layer. Each insulated conductor comprises a hot-dip tinned copper wire conductor. The outer side of the hot-dip tinned copper wire conductor is provided with a double-deck mica tape layer and an irradiation crosslinking polyolefin insulating layer successively. The antistatic high-performance mine signal transmission cable of the utility model has advantages, such as excellent antistatic performance, low capacitance, low inductance, fire-retardant performance, anti-explosion performance, etc.
Description
Technical field
The utility model relates to cables manufacturing technical field.
Background technology
Along with the quickening of China's modernization, demand for energy strengthens, promote coal industry field fast development, large quantities of modernization collieries are built to the degree of depth, condition complicated, severeization and are shifted, underground high humidity, gas density are high, static gathers many, inflammable and explosive and strong electromagnetic width and the adverse circumstances such as penetrates and constantly occur, unsafe factor increases increasingly.Cable is a kind of important electric installation in colliery, is ensureing the normal safe operation of electromechanical equipment, and Safety of Coal Mine Production, has larger effect in enhancing productivity.For intensified safety measure, enhance productivity, cause down-hole more to need the input of scientific and reasonable high-tech watch-dog, common mining signal cable can not adapt to the request signal transmission of these high-tech watch-dogs far away, more needs multi-functional, high performance signal-transmitting cable to connect line for this reason and is equipped with it.
Utility model content
The utility model is to overcome the deficiency that common cable exists, and provides a kind of antistatic, high flame retardant, explosion-proof, transmission rate is high, the mining signal transmission cable of strong anti-interference performance.
The utility model comprises cable core, set gradually stranding lapping layer, the total screen of aluminium-plastic tape, low-smoke non-halogen flame-retardant inner covering, vertical bag stainless steel wrinkle band armour, anti-electrostatic fire retardant PVC external sheath layer in cable core outside, in the total screen of described aluminium-plastic tape inner side, the first drainage thread is set; Between described cable core and stranding lapping layer, fire-retardant packed layer is set; Described cable core comprises some groups of cores, and the core described in every group comprises respectively pair twist insulated electric conductor in groups, sets gradually aluminium-plastic tape sub-shield and polyester film lapping layer in pair twist insulated electric conductor outside in groups; In aluminium-plastic tape sub-shield inner side, the second drainage thread is set; Insulated electric conductor described in every comprises respectively hot dipped tinning copper wire conductor, sets gradually double-deck mica belt and irradiation crosslinked polyolefin insulating layer in hot dipped tinning copper wire conductor outside.
To be that multiply tinned copper wire is stranded form the utility model drainage thread, and cross section is not less than 0.2mm
2.The utility model is rational in infrastructure simple, manufacturing science, and cost is low, and serviceability is good, and this product is provided with aluminium-plastic tape composite shielding layer, makes cable have the advantages that external diameter is little, lightweight, more soft, moistureproof, shield effectiveness is good.Insulation adopts irradiation crosslinked polyolefin insulating material, and inner covering material is low-smoke non-halogen flame-retardant material; Protective cover material adopts anti-electrostatic fire retardant PVC sheath PP Pipe Compound, has ensured that product has excellent antistatic, low electric capacity, low inductance, fire-retardant, explosion-proof characteristic, has met the performance requirement of mine signal-transmitting cable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable core, set gradually stranding lapping layer 1, the total screen 2 of aluminium-plastic tape, low-smoke non-halogen flame-retardant inner covering 3, vertical bag stainless steel wrinkle band armour 4, anti-electrostatic fire retardant PVC external sheath layer 5 in cable core outside, in the total screen of aluminium-plastic tape 2 inner sides, the first drainage thread 6 is set; Fire-retardant packed layer 7 is set between cable core and stranding lapping layer 1; Cable core comprises two groups of cores 8, and every group of core 8 comprises respectively pair twist insulated electric conductor 9 in groups, sets gradually aluminium-plastic tape sub-shield 10 and polyester film lapping layer 11 in pair twist insulated electric conductor 9 outsides in groups; In aluminium-plastic tape sub-shield 10 inner sides, the second drainage thread 12 is set; Every insulated electric conductor 9 comprises respectively hot dipped tinning copper wire conductor 13, sets gradually double-deck mica belt 14 and irradiation crosslinked polyolefin insulating layer 15 in hot dipped tinning copper wire conductor 13 outsides.
