Abstract
The invention discloses a mine anti-interference highly inflaming-retarding signal transmission cable, and relates to the technical field of cables, in particular to the mine anti-interference highly inflaming-retarding signal transmission cable. The signal transmission cable comprises four sets of cablecores which are mutually stranded, and an inflaming-retarding taped covering layer, an aluminum foil taped covering master shielding layer, an aluminum-polyethylene bonding protection layer, an inner protection layer, a longitudinal covering corrugated steel tape armoring layer and an outer protection layer are sequentially arranged outside the stranded cable cores. A waterproof filling layer is arranged between the cable cores and the inflaming-retarding taped covering layer. Each cable core comprises two strands of insulated conductors which are mutually stranded, and a first waterproof taped covering layer, a split-phase shielding layer and a second waterproof taped covering layer are sequentially arranged outside each set of stranded insulated conductors. Each strand of insulated conductor comprises a conductor, and the conductor is wrapped with an insulating layer. The mine anti-interference highly inflaming-retarding signal transmission cable has the advantages of being capable of retarding flame, low in inductance, high in transmission speed, strong in anti-interference capacity, good in anti-explosion performance, good in environment-protection performance, reasonable in structure, advanced in technology and the like.
Description
Technical field
The present invention relates to the cable technology field, particularly a kind of anti-interference high flame retardant mining signal transmission cable.
Background technology
China is a big coal country, and in recent years, the raw coal annual production had all surpassed 2,000,000,000 tons, and coal has played very important effect in the construction and development of Chinese national economy.Quickening along with China's modernization, the coal industry field fast development, the scale of coal mining and putting more effort, large quantities of modernized colliery construction change to the degree of depth, condition complicated, abominableization, underground high humidity, gas density is high, inflammable and explosive and the strong electromagnetic width of cloth adverse circumstances such as is penetrated and constantly occurred.The mine of high gas or coal and Gas Outburst surpasses 15% in the particularly little colliery, and the mine with coal dust explosion hazard accounts for 91.35%, wherein has intense explosion up to 57.71% mine.Unsafe factor increases increasingly, mine safety accidents takes place frequently, for the intensified safety measure, enhance productivity, cause the down-hole more to need scientific and reasonable anti-interference high flame retardant mining signal transmission cable, especially the promotion and application of modernized high-tech watch-dog are more and more in the mine automation comprehensive monitoring systems such as colliery complex automatic system, coal separation field collection control dispatching patcher, and common mining signal cable can not adapt to the requirement of these high-tech watch-dogs far away.For this reason, more needing multi-functional, high performance signal-transmitting cable to connect line is equipped with it.
Summary of the invention
The object of the invention is to solve the existing cable signal transmission rate slow in order to adapt to the modern technologies equipment Requirement, and the shortcoming that accuracy rate is not high provides a kind of anti-interference high flame retardant mining signal transmission cable.
The present invention includes four groups of mutual stranded cores, outside described stranded core, set gradually fire-retardant lapping layer, the wrapped total screen of aluminium foil, aluminum-polyethylene bonding sheath, sheath, vertical bag wrinkle steel-tape armouring layer and outer jacket; The packed layer that blocks water is set between described core and fire-retardant lapping layer; Described every group of core includes two strands of mutual stranded insulated electric conductors, sets gradually first lapping layer, phase-splitting screen and second lapping layer that blocks water that blocks water outside described every group of stranded insulated electric conductor; Described per share insulated electric conductor comprises respectively conductor, distinguishes the wrap insulate layer outside described per share conductor.
Conductor of the present invention is by stranded the forming of high-quality hot dipped tinning copper wire, adopt soluble poly tetrafluoroethene insulating barrier, high flame retardant polyolefin sheath, blue low-smoke halide-free fireproof composite polyolefine material outer jacket has fire-retardant, the advantages such as inductance is low, transmission rate is high, strong anti-interference performance, the capability of antidetonance are excellent, good environmental protection.The present invention is rational in infrastructure, technique is advanced.
