Abstract
Disclosed is a flexible inorganic insulated fireproof cable with insulated damp-proof layer, which is characterized in that the cable comprises a plurality of cable cores orderly coated with an insulated layer, an insulated damp-proof layer (3) and a conductor (1) weaving or winding a reinforced layer (4) from inside to outside; an insulated lining (6) and a metallic sheath layer (7) orderly coated outside the cable cores; and a filler (5) composed of an inorganic filling rope filled in the interval between the insulated lining (6) and the cable cores.
Description
Technical field
The utility model patent relates to a kind of cable, relates to a kind of flexible inorganic insulation fireproof cable with insulation and moisture layer specifically.
Background technology
Traditional mineral insulated cable is to be insulation with the magnesia powder, and it has excellent performance such as fire-resistant, explosion-proof, high temperature resistant, corrosion-resistant, mainly is applicable to fire-fighting system, fire hazard district, high temperature occasion and important, crucial place.Supply line can power in the regular hour when assurance was caught fire, and was convenient to the evacuation of personnel and valuable cargo.But the manufacturing process of this cable is loaded down with trivial details, and equipment investment is big.Drum length of cable is limited, lays as long distance, just needs to increase transition joint.And the increase of transition joint will certainly increase the possibility that product leaks gas.The easy moisture absorption of magnesia powder causes cable to descend at the insulation resistance of joint after the moisture absorption, influence electric property.In addition, the bending property of cable is relatively poor, installs and lays inconvenience, and the scope of application is subjected to certain limitation.Since the manufacturing process complexity, the energy consumption height, and the finished product rate is low, causes cable price height, is not easy to promoting the use of of product.
Summary of the invention
The purpose of this utility model is just at existing weak point in the above-mentioned prior art and a kind of flexible inorganic insulation fireproof cable with insulation and moisture layer.
Flexible inorganic insulation fireproof cable with insulation and moisture layer of the present utility model comprises the many cable cores that are enclosed with the conductor composition of insulating barrier, insulation and moisture layer, braiding or wrapped enhancement layer from the inside to the outside successively, be wrapped in cable core outer insulation lining and metal sheath layer successively, be filled with the packing material that adopts inorganic gasket for packing to constitute in the gap in insulation lining and between cable core.
The utility model can also be enclosed with the external sheath layer that adopts any one material in LSOH anti-flaming plastics, polyvinyl chloride or the corrosion-inhibiting coating according to actual needs outside metal sheath layer.
Conductor described in the utility model adopts real core copper conductor or multiply to press twisted copper conductors and makes, and its cross sectional shape is circle or sector structure.This structure is easy to processing, and factory length is unrestricted, has certain flexibility and bendability during use, is convenient to lay.
Insulating barrier described in the utility model adopts wrapped the forming of multilayer inorfil band; For increasing the mechanical strength of insulating barrier, described braiding or wrapped enhancement layer employing inorfil weave or the glass fiber strap is wrapped forms, and this structure also can play tight bundle and heat-blocking action.
Inorganic gasket for packing inserts described in the utility model can play the effect that prevents that moisture from invading.
Metallic sheath described in the utility model adopts copper or stainless steel, can select embossing or embossing structure not according to operating position.
Compared to existing technology, the beneficial effects of the utility model are as follows:
(1) softness is good
Conductor and metal sheath adopt the design of soft junction structure, and longer than factory length with drawing formula fireproof cable, the process-cycle is short, operation is few; Transition joint is few, and is easy for installation, can effectively reduce failure rate.
(2) fire protecting performance excellence
Because the cable element is inorganic material, has determined the non-ignitibility of cable itself.Product meets BS, IEC standard, can bear 950 ℃, 3 hours burning test (containing spray, mechanical shock) under charged situation, and guarantees the normal operation of circuit.
(3) temperature resistant grade height, transmission capacity are big.
There is not the possibility of heat ageing in insulating material, can be 500 ℃ of following short-term operation, and 300 ℃ of following long-time running.According to the common cable of same cross-sectional, this product can not only transmit higher electric current and can bear bigger overload.
(4) moisture effect is good
Outside insulation, increased damp-proof layer, added that metallic sheath has good sealing function, even cable can not reduce insulation level yet under long-term cold situation.
(5) has anti-corrosion function
In the serious occasion of chemical corrosion, select stainless steel sleeve for use, can play antiseptic effect.Increase corrosion-inhibiting coating according to user's needs.
(6) shielding
Metallic sheath has good shield effectiveness, can eliminate the electromagnetic pollution to surrounding environment.
(7) Halogen, low cigarette, fire-retardant
Cable adopts on-fuel inorganic matter insulation, halogen-free and low-smoke flame-retardant polyolefin sheathed.Carry out the smoke density test according to IEC 61034, minimum light transmittance reaches more than 60%.
(8) good mechanical property
Can bear the effect of mechanical external forces such as stronger drawing, extruding, impact, distortion.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
Embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in the figure, flexible inorganic insulation fireproof cable with insulation and moisture layer of the present utility model comprises the many cable cores that are enclosed with conductor 1 composition of insulating barrier 2, insulation and moisture layer 3, braiding or wrapped enhancement layer 4 from the inside to the outside successively, be wrapped in cable core outer insulation lining 6 and metal sheath layer 7 successively, be filled with the packing material 5 that adopts inorganic gasket for packing to constitute in insulation lining 6 and in the gap between cable core.
The utility model can wrap up the external sheath layer 8 that one deck adopts any one material in LSOH anti-flaming plastics, polyvinyl chloride or the corrosion-inhibiting coating according to actual needs again outside metal sheath layer.
Insulating barrier 2 described in the utility model adopts wrapped the forming of multilayer inorfil band; For increasing the mechanical strength of insulating barrier, described braiding or wrapped enhancement layer 4 employing inorfils weave or the glass fiber strap is wrapped forms, and this structure also can play tight bundle and heat-blocking action.
