Abstract
The invention discloses a kind of novel environment friendly explosion-proof place intrinsic safety cables, belong to cable application technical field, a kind of novel environment friendly explosion-proof place intrinsic safety cable, including three cable cores, the inside of each cable core is equipped with the core of two groups of pair twists, core described in every group includes a copper conductor, the first semiconductive nylon tape around the outside of copper conductor and the crosslinked polyetylene insulated layer that is extruded on the outside of the first semiconductive nylon tape, it may be implemented preferably to insulate, shielding properties, electromagnetic interference can effectively be prevented, it is small by external magnetic field perturbed force, and it prevents fires, explosion-proof performance is excellent, it has a safety feature, intensity is high, resistance to compression, good pressure-resistant performance, it is poor to solve existing cable physical property, smoke amount is big when burning, burning can lead to the problem of a large amount of poisonous and harmful property gases.National standard can be met or exceeded compared to traditional intrinsic safety cable properties, is better than existing similar cable.
Description
Technical field
The present invention relates to cable application technical fields, more specifically to a kind of explosion-proof place intrinsic safety of novel environment friendly
Cable.
Background technique
Cable is the cable for the similar rope that by several or several groups of conducting wires (every group at least two) are twisted, every group of conducting wire
Between mutually insulated, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Cable has interior logical
Electricity, the feature of external insulation.
With science and technology fast development, electron controls technology it is commonly used, electricity piece is more and more, and electric wire also can
More and more, the especially industry such as chemistry and petroleum requires the explosion-resistance characteristic of cable higher and higher.This be need solve greatly ask
How topic makes a large amount of harness in the safer reasonable Arrangement in the explosion-proof place such as chemical industry, keeps the process of industry manufacture production safer,
As the explosion-proof place problems faced such as chemical industry manufacturing industry.
Summary of the invention
1. technical problems to be solved
Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a kind of novel environment friendly explosion-proof place intrinsic safety electricity
Cable may be implemented preferably insulation, shielding properties, can effectively prevent electromagnetic interference, small by external magnetic field perturbed force and anti-
Fire, explosion-proof performance are excellent, have a safety feature, and intensity is high, resistance to compression, good pressure-resistant performance, solve existing cable physical property it is poor,
Smoke amount is big when burning, a large amount of poisonous and harmful property gases can be led to the problem of by burning.
2. technical solution
To solve the above problems, the present invention adopts the following technical scheme that.
The inside of a kind of novel environment friendly explosion-proof place intrinsic safety cable, including three cable cores, each cable core is equipped with two
The core of group pair twist, core described in every group includes a copper conductor, the first semiconductive nylon around the outside of copper conductor
Band and the crosslinked polyetylene insulated layer being extruded on the outside of the first semiconductive nylon tape, the cable core further include outside two groups of cores by
Interior and the first polyester belt, the first tinned copper wire woven shield and the second polyester belt that wrap up outside, cable core described in each adjacent two
Between fitting be provided with triangle rubber skeleton, fiber filled layer is filled with inside each triangle rubber skeleton, three
Third polyester belt is surrounded on the outside of a cable core, the outside of the third polyester belt is successively enclosed with the second semiconductive from inside to outside
Nylon tape, the second tinned copper wire woven shield, armored protective layer, low-smoke non-halogen flame-retardant cross-linking radiation polyolefin jacket.
Further, three cable core arrangements triangular in shape, and the setting that contacts with each other.
Further, solid copper conductor is made using No. 1 recycled copper in the copper conductor, it is ensured that cable is connect with equipment
In the case where prevent virtual connection occur, and conductor more rounding, conductor external electric field is more evenly.
Further, it is filled out filled with glass silk floss in the internal voids of first polyester belt and the third polyester belt
Layer is filled, glass silk floss has preferable fire prevention, refractory ability, effectively increases fireproofing of cable performance.
Further, the fiber filled layer is made of glass fibre, polypropylene fibre mixing, glass fibre, polypropylene
Fiber 2:1 in mass ratio is mixed, and in the inside fiberfill fibers filled layer of triangle rubber skeleton, can effectively enhance triangle
The compression cushion performance of shape rubber skeleton, effectively raises the intensity of cable.
Further, it is equipped with filling pipe inside the third polyester belt, expelling mouse agent is filled with inside the filling pipe, it is described
Expelling mouse agent is solid expelling mouse agent, and expelling mouse agent can be used to repellent mouse, and mouse is made to be unwilling close to cable, thus effective protection cable
It is not baited by mouse.
Further, the armored protective layer uses aluminium alloy, and armor made of aluminium alloy can be to cable entirety shape
At effective protection, the integral strength of cable is improved.
