Description

Cable for power transformation cabinet

Technical Field

The utility model relates to the technical field of cables, in particular to a cable for a power transformation cabinet.

Background

At present, the cable is widely used in various fields for power transmission and signal transmission, the outer layer of the cable is generally made of flexible materials, so that the fireproof performance of the cable is poor, the cable is easy to generate spontaneous combustion and other conditions due to aging after long-term use, cable core wires which generate spontaneous combustion can be rapidly transmitted to other strand core wires, the spontaneous combustion of the whole cable is caused, and flame and fire accidents are rapidly transmitted.

The fire-proof performance of the existing fire-proof cable is general, the fire-proof time can be only temporarily increased, the flame cannot be well blocked, and therefore the flame can be transmitted continuously.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a cable for transformer cabinet, includes wire core 1, wire core 1's outside parcel one deck fixed network 2, the parcel of fixed network 2 has waterproof layer 3, waterproof layer 3 is a waterproof ventilated membrane, waterproof ventilated membrane mainly has the three-layer to constitute, PP glues the non-woven fabrics, PE polymer ventilated membrane, PP glues the non-woven fabrics, under the state of steam, the water particle is very tiny, according to capillary motion's principle, can permeate the capillary smoothly to the opposite side to take place the ventilative phenomenon. When water vapor is condensed into water drops, particles become larger, due to the action of the surface tension of the water drops (mutual 'pulling and balancing' between the water molecules), the water molecules can not smoothly separate from the water drops and permeate to the other side, namely, the water permeation is prevented, so that the vapor permeable membrane has a waterproof function, the waterproof layer 3 is externally wrapped by the heat dissipation layer 4, the heat dissipation layer 4 is a graphite heat dissipation fin, is a nano advanced composite material, is suitable for any surface uniform heat conduction and has an EMI electromagnetic shielding effect, the heat dissipation hole 5 is formed inside the heat dissipation layer 4, the buffer layer 6 is externally wrapped by the heat dissipation layer 4, the buffer layer 6 is an elastic device and is made of rubber, when the cable is extruded by external force, the pressure on the wire core 1 is reduced through the buffer layer 6, the fireproof layer 7 is wrapped outside the buffer layer 6, the fireproof layer 7 is made of silicon carbide, and has stable chemical performance, The heat dissipation hole 5 penetrates through the heat dissipation layer 4 and the fireproof layer 7, and the bottom of the heat dissipation hole is in contact with the waterproof layer 3.

The working principle is as follows: the utility model provides a cable for transformer cabinet when using, be in the same place wire core 1 is fixed through fixed network 2, the carborundum that contains in the flame retardant coating 7 of outmost parcel has the chemical property stability, the coefficient of heat conductivity is high, the coefficient of thermal expansion is little, the characteristic that wear resistance is good, this a cable for transformer cabinet passes through waterproof layer 3 and reaches waterproof ventilative effect, release the heat through heat dissipation layer 4 and louvre 5, reduce the damage to wire core 1 under the pressure effect through buffer layer 6.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
