Abstract
The utility model provides a flexible mineral insulation fire resisting cable of 1kV, is at outer package pottery flame retardant coating and the high fire-retardant low smoke polyolefin sheath of nothing in proper order around the core, and the core is including setting up mineral mica tape, the fire-retardant fire resisting insulation layer of pottery nothing in proper order around the package outside the conductor of center department. Flame-retardant filling is arranged among the multiple groups of used wire cores and between the wire cores and the high-flame-retardant halogen-free low-smoke polyolefin sheath. The utility model uses the mineral mica tape, the ceramic halogen-free low-smoke polyolefin flame-retardant fire-resistant insulating layer and the ceramic fireproof layer, thereby improving the flame-retardant property of the cable to the maximum extent; and if high temperature is met, each layer of protective layer can not be decomposed at high temperature to release toxic halogen substances, the overall safety performance of the cable is improved, the cable is safer and more reliable, and the environment-friendly effect is realized. The utility model discloses a no matter what layer sets up, all embodied flexibility and easy mobility, can be more convenient in installation, joint, crooked use.
Description
Technical Field
The utility model relates to the technical field of cables, a flexible mineral insulation fire resisting cable of 1kV is provided very much.
Background
The mineral insulation fireproof cable in the prior art uses a copper conductor as a wire core, and a copper sheath is arranged outside the copper conductor. The structure has the disadvantages that the cable is extremely difficult to bend and has great limitation in the transportation process; and the production process can not meet the requirements of long-size products.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a long service life class flexible cable.
The utility model particularly provides a flexible mineral insulation fire resisting cable of 1kV winds package pottery flame retardant coating 7 and high fire-retardant no halogen low cigarette polyolefin sheath 2 in proper order at 1 skin of sinle silk, and sinle silk 1 is including setting up mineral mica tape 4, the fire-retardant fire-resistant insulating layer 5 of pottery no halogen low cigarette polyolefin of package in proper order outside the copper conductor 3 of center department. Flame-retardant filling 6 is arranged among the multiple groups of used wire cores 1 and between the wire cores and the high-flame-retardant halogen-free low-smoke polyolefin sheath 2.
The utility model discloses a conductor adopts copper wire stranded filament transposition to form the copper conductor, wraps the one deck mineral mica tape at the conductor outer surface around, and the fire-retardant fire-resistant insulating layer of crowded package one deck pottery halogen-free low smoke polyolefin fills the stranding after that, adopts pottery porcelain ization flame retardant coating and high fire-retardant halogen-free low smoke polyolefin sheath as the oversheath at last.
The utility model uses the mineral mica tape, the ceramic halogen-free low-smoke polyolefin flame-retardant fire-resistant insulating layer and the ceramic fire-resistant layer, thereby improving the flame-retardant and fire-resistant performances of the cable to the maximum extent; and if high temperature is met, each layer of protective layer can not be decomposed at high temperature to release toxic halogen substances, the overall safety performance of the cable is improved, the cable is safer and more reliable, and the environment-friendly effect is realized. The utility model discloses a no matter what layer sets up, all embodied flexibility and easy mobility, can be more convenient in installation, joint, crooked use.
Drawings
The invention is described in further detail below with reference to the drawings in the specification:
fig. 1 is a schematic cross-sectional view of the present invention.
Description of the symbols of the drawings:
1 wire core, 2 high flame-retardant halogen-free low-smoke polyolefin sheath, 3 copper conductor, 4 mineral mica tape, 5 ceramic halogen-free low-smoke polyolefin flame-retardant fire-resistant insulating layer, 6 flame-retardant filling and 7 ceramic fire-resistant layer.
Detailed Description
Example 1
The utility model provides a flexible mineral insulation fire resisting cable of 1kV, is at 1 skin of sinle silk in proper order around package pottery flame retardant coating 7 and high fire-retardant halogen-free low smoke polyolefin sheath 2, sinle silk 1 is including setting up mineral mica tape 4, the fire-retardant fire resisting insulation layer 5 of pottery halogen-free low smoke polyolefin around the package in proper order outside 3 copper conductors of center department. Flame-retardant filling 6 is arranged among the multiple groups of used wire cores 1 and between the wire cores and the high-flame-retardant halogen-free low-smoke polyolefin sheath 2.
In the embodiment, the mineral mica tape, the ceramic halogen-free low-smoke polyolefin flame-retardant and fire-resistant insulating layer and the ceramic fireproof layer are used, so that the flame retardance and fire resistance of the cable are improved to the greatest extent; and if high temperature is met, each layer of protective layer can not be decomposed at high temperature to release toxic halogen substances, the overall safety performance of the cable is improved, the cable is safer and more reliable, and the environment-friendly effect is realized. No matter what layer of this embodiment sets up, has all embodied flexibility and easy mobility, can be more convenient in installation, joint, crooked use.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
Moreover, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
