Abstract
A fireproof cable, belonging to cable compound technology, consists of a copper core inner conductor, an insulating layer and a protecting pipe. The insulating layer coating the copper core inner conductor is made of ceramic magnesium oxide. And the protecting pipe outside the insulating layer is a stainless corrugated pipe. Taking an argon arc welding stainless corrugated pipe as the protecting pipe of the copper core inner conductor can increase the length of cables and make middle joints unnecessary. Besides, the security is high and the cable section can be larger in design. In particular, fireproof cables of 4-wire 50 mm^2 diameter and above can be produced. Other than these, the advantages are of low cost, relatively larger bending radius of cables and construction convenience.
Description
Technical field
This is practical to relate to a kind of cable, belongs to the CABLE MATERIALS technical field, refers in particular to a kind of fireproof cable.
Background technology
The outer pillar of the conductor of fireproof cable adopts copper pipe at present, and cable conductor is big, and copper pipe also will increase, the restriction that produced by copper pipe, and commercially available fireproof cable especially multicore is counted fireproof cable, and its sectional area ratio is less, 50mm
2Above heavy in section multicore fireproof cable can't be produced, and copper pipe sheath flexibility is poor in addition, almost can't be crooked, and the inconvenience construction, its cable cost is higher; The single core mineral insulated cable in heavy in section on the market, the copper pipe sheath can only prolong with stretching mode, and its fertile distance is shorter, the longest generally about 100 meters, need multistage to connect, if long distance connects, the transition joint that needs is many, easily water inlet, and security of products can be poor.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, provide a kind of sectional area big, design rice number can need not transition joint according to customer need surely and connect, security performance is good and have an easy working fireproof cable of flexibility, main innovation is that the outer insulating barrier of copper in-core conductor is ceramic magnesium oxide, the protecting pipe of insulating barrier adopts stainless steel ripple steel pipe, specifically implement like this: fireproof cable, comprise copper in-core conductor, insulating barrier, protecting pipe, it is characterized in that the outer insulating barrier of copper in-core conductor is ceramic magnesium oxide insulating barrier, the outer protecting pipe of insulating barrier is a stainless steel ripple steel pipe.This stainless steel ripple steel pipe adopts the argon arc welding, does not need annealing in the production process, little power consumption, production cycle is fast, need not extruding, small investment, the place is few, and with the protecting pipe of its mineral wool cable, the protecting pipe sectional area can enlarge, can produce heavy in section fireproof cable, in addition, cable bending radius in construction is bigger, made things convenient for construction, and can determine length as required, need not to connect that security performance is guaranteed with transition joint.
Fireproof cable of the present utility model can be single core fireproof cable, also can the multicore protective cable, the protecting pipe of single core fireproof cable is equipped with stainless steel wire outward and knits cover, increases the flexibility of cable, production cost is low, and stainless steel silk weaving cover is outer also to be equipped with anticorrosion or the decoration sheath.Core body as fireproof cable is made of copper in-core conductor, insulating barrier, protecting pipe, outsourcing high-temperature resistant inner lining layer behind the stranded stranding of the multicore of multicore fireproof cable, the cable body is with the high temperature resistant inserts filling of low smoke, zero halogen, and inner covering also is equipped with metal tape armour lapping layer, high-strength fire-retardant mica tape and stainless steel wire braiding armouring anticorrosioning sheath outward successively.
The utility model adopts argon arc welding stainless steel wave line steel pipe to make the protecting pipe of copper in-core conductor, can increase cable length and need not use transition joint, and security performance height, the cross-section of cable amass and can design greatlyyer, particularly can produce 4 core 50mm
2Above fireproof cable, production cost is low, and Cable Bending Radius is bigger, easy construction.
