Further optimize this technical scheme, be provided with the through-hole on the support bar.

Further optimizing the technical scheme, the waterproof layer is made of ethylene propylene rubber.

Further optimizing the technical scheme, the outer sheath is made of heat-conducting rubber, and the heat-conducting rubber is silicon rubber mixed with boron nitride powder.

Compared with the prior art, the utility model has the following advantages: 1. a channel which can allow water to pass is formed between the adjacent support bars, and cooling water flows through the channel to cool the cable and prevent the temperature of the cable from rising; 2. the through holes are formed in the supporting bars, cooling water can flow through the through holes, and the cooling effect on the supporting bars is enhanced; 3. the wrapping layer is provided with the waterproof layer outward, can prevent that cooling water from getting into within wrapping layer and the wrapping layer.

Drawings

Fig. 1 is a schematic structural diagram of a high-temperature-resistant high-performance low-voltage power cable.

In the figure: 1. an outer sheath; 2. a supporting strip; 21. a through hole; 3. a waterproof layer; 4. a wrapping layer; 5. a filling layer; 6. an insulated wire core; 7. a joint; 71. a cavity; 72. a water pipe.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: combine fig. 1 to show, a high temperature resistant high performance low pressure power cable, including a plurality of insulation core 6 and surrounding layer 4, insulation core 6 is inside to be the conductor, the outside is the insulating layer, be provided with filling layer 5 between insulation core 6 and the surrounding layer 4, the surrounding layer 4 outside is provided with waterproof layer 3, 3 outsides of waterproof layer are provided with oversheath 1, be provided with a plurality of support bars 2 between oversheath 1 and the waterproof layer 3, formed the passageway that can let water pass through between the adjacent support bar 2. This cable is still including connecting 7, connect 7 and install the both ends at the cable, it is cylindric to connect 7, connect 7 inside cavity 71 and the opening of one side of being provided with, opening side orientation support bar 2, the outside that connects 7 is provided with water pipe 72, water pipe 72 is linked together with cavity 71, it is inboard that joint 7 is located the cladding layer 4 outside and is located oversheath 1, connects 7 and bonds together with cladding layer 4 and oversheath 1, and is in encapsulated situation to prevent to leak. The insulated wire core 6 penetrates through the inside of the cylindrical joint 7 and extends outwards, so that the wiring is convenient.

The support bar 2 is provided with the through holes 21, cooling water can flow through the through holes 21, and the cooling effect is enhanced.

The waterproof layer 3 is made of ethylene propylene rubber, so that the waterproof property is good, and cooling water cannot permeate into the wrapping layer 4.
