Abstract
The utility model provides an irregular-shaped inflaming retarding leading wire. By improving the manufacture process and designing irregular-shaped appearance, flexibility, impact resistance and abrasion resistance of a cable are improved. A nylon rope is arranged between conductors, an insulation protective sleeve layer is arranged outside the nylon rope, protrusions are arranged outside the insulation protective sleeve layer, material use amount is small, pressing and smashing resistance, extrusion resistance and abrasion resistance of the cable are improved, the wire is resistant to folding and not prone to break, a thinned copper wire is not easy to oxidize, connection is firm, impact resistance is improved, and used materials are high in tensile strength and abrasion resistance and good in inflaming retarding performance.
Description
Technical field
The present invention relates to the electric wire field, is a kind of power connection cable that can explosion is used when various mining specifically.
Background technology
The mine blasting bus is used more extensive at present, mostly adopt steel core, iron core or copper core strand to knit line, some Coal Exploitations MBM shot firing cable of producing according to MT930, these shot firing cables are low due to the conductor suppleness, easily damage without restrictive coating or the thinner cable of restrictive coating, reuse number of times few, safeguard that labour cost is high, poor safety performance.
Summary of the invention
For solving an above difficult problem, the invention provides the fire-retardant shot firing cable of a kind of abnormal shape, improve and design special-shaped outward appearance by manufacturing process, improved cable pliability, impact resistance and resistance to wear.
The present invention is achieved in that nylon rope is set between conductor, the outer setting insulation restrictive coating of holding concurrently, and insulation hold concurrently restrictive coating outside is protruding.
The invention has the beneficial effects as follows: concavo-convex minimizing material usage has increased that the cable resistance to compression is pounded, extruding and anti-wear performance; Stranded leading has flexibility, folding be not easy the broken string, tinned copper wire is difficult for oxidation, with initiator be connected with detonator firm; Nylon rope makes the anti-kinking of cable, increases tensile strength, prevents that conductor from opening circuit; The insulation sheath of holding concurrently once extrudes moulding, reduces the course of processing, and the construction of cable is compact, and impact resistance is strengthened, and uses material to have that tensile strength is high, anti-wear performance good, fire resistance is good.
Description of drawings
Be described further below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
In figure 1, projection, 2, conductor, 3, nylon rope, 4, the insulation restrictive coating of holding concurrently.
Embodiment
As shown in the figure, nylon rope 3 is set between conductor 2, the outer setting insulation restrictive coating 4 of holding concurrently, insulation hold concurrently restrictive coating 4 outside are protruding 1.
Bus one is terminated on blaster, and nylon rope 3 is stressed, and conductor 2 cores do not stress, and can avoid like this terminals to be pulled the twisting conductor thread core and fracture; The cap sensitive line inserts respectively other end conductor 2, and nylon rope 3 is beaten in succession with the cap sensitive line and connect, and prevents from pulling the cap sensitive line is extracted from conductor 2.The slag of cleaning pile things on cable is completed in explosion, has been wound around bus in order to using next time.As the restrictive coating 4 of holding concurrently of insulating damages and should repair, and a conductor exposes and uses insulating tape wrapped; Two conductors expose that to cast aside 15 centimetres of left and right along intermediate projections 1 edge wrapped with insulating tape to each conductor respectively, then are set with protective jacket; As break and repair with the link of standby insulated conductor, and suitably protect, in bus, the double restrictive coating 4 of nylon rope 3 and insulation with strength, can prevent during use that the joint from pulling open like this.
Claims (1)
1. the fire-retardant shot firing cable of abnormal shape, is characterized in that, nylon rope is set between conductor, the outer setting insulation restrictive coating of holding concurrently, and insulation hold concurrently restrictive coating outside is protruding.
