Abstract
The utility model discloses a fireproof cable comprising conductors, insulating layers, and an insulating sheath. A fireproof layer is disposed between the insulating layers and the insulating sheath and comprises a mica tape and a glass fiber tape which are wound towards opposite direction. Therefore, the winding seam of the mica tape and that of the glass fiber tape can be mutually shielded. Namely, no weak area exists in the fireproof layer and the glass fiber tape has relatively low cost. Low-smoke halogen-free filling adhesive tapes are further filled between the insulating layers and the fireproof layer, and between the fireproof layer and the insulating sheath. The low-smoke halogen-free filling adhesive tape may release moisture under high temperature to perform a cooling effect. A good fireproof function can be achieved by not disposing more fireproof layers. As a result, cost is further saved. In conclusion, the fireproof cable has a good fireproof performance and relatively low cost.
Description
Technical field
The utility model relates to a kind of fireproof cable, belongs to the cables manufacturing technical field.
Background technology
Along with developing rapidly of China's economy, various architectural engineerings are with unprecedented scale and speed development, and high-rise building covers higher and higher, thereby also day by day harsh to the requirement of electric equipment.Yet, increased gradually owing to the electric fire that causes in recent years, and the fire that wherein causes owing to the electric wire reason occupies sizable ratio.For this reason, people extremely pay close attention to the flame retardant effect of electric wire, at conductor outer cladding fire resistant belt, at fire resistant belt outer cladding insulating sleeve, can embody the fireproofing of cable performance again, and this cable is accepted by people because having outstanding flameproof effect.
Current industry usually adopts in described conductor periphery and coat the multi layer cloud master tape, yet there is following defective in this kind way: the extra cost that the increase of multi layer cloud master tape is larger for strengthening the fireproofing of cable performance; Blind stitching between the mica tape of adjacent layer is easily overlapping and form vulnerable areas, affects the fireproofing of cable performance.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to provide a kind of fireproof cable, and this fireproof cable fire protecting performance is good and cost is relatively low.
A kind of fireproof cable that the utility model provides, it comprises conductor, insulating barrier and insulating sleeve, between described insulating barrier and described insulating sleeve, be provided with fireprotection layer, described fireprotection layer comprises by the mica tape of rightabout coiling and glass fiber tape, further in being filled with the low smoke and zero halogen gum filler that at high temperature discharges cooling effect the moisture between described insulating barrier, described fireprotection layer and the described insulating sleeve.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
A kind of fireproof cable that the utility model provides, it comprises conductor, insulating barrier and insulating sleeve, between described insulating barrier and described insulating sleeve, be provided with fireprotection layer, described fireprotection layer comprises by the mica tape of rightabout coiling and glass fiber tape, further in being filled with the low smoke and zero halogen gum filler that at high temperature discharges cooling effect the moisture between described insulating barrier, described fireprotection layer and the described insulating sleeve; Described fireprotection layer comprises by the mica tape of rightabout coiling and glass fiber tape, thereby, described mica tape and described glass fiber tape blind stitching separately can block mutually, be that described fireprotection layer does not exist vulnerable areas, and the cost of described glass fiber tape is relatively cheap, in addition, in described insulating barrier, be filled with between described fireprotection layer and the described insulating sleeve and at high temperature discharge the low smoke and zero halogen gum filler that moisture plays the cooling effect, more multi-layered described fireprotection layer can be set and reach preferably fire-proof function, thereby, further save cost, in summary, the fireproof cable fire protecting performance that the utility model provides is good and cost is relatively low.
