XLPE insulated high voltage power cable is used to transmit power on the power transmission and distribution line of A.C.50Hz, rated voltage 35kV or lower, and also used for Subway,Power station,Factory and Mine.It can be installed underground, in pipe, in trench or in tunnel.
XLPE Cable not only has excellent electric character, mechanical character, heat and aging-resistant character, environmental stress-resistant character and chemical corrosion- resistant character, but simple structure, light weight, no restriction by laying drop, and high temperature allowance for long-term working as well.

Specific property for usage of 110kv~220kv xlpe high-voltage cable
1. Cable's conductor highest working temperature is allowed up to 90⺠c, and overload when meet an emergency is 130⺠c, when short circuit (in � 5 seconds) the highest temperature is 250⺠c
2. When installing or laying cable, the ambient temperature should be less than -20⺠c, and have to give a preheat to cable.
3. The minimum bending diameter(in follow the table):
Note: in form, d0 is a real test value to cable's outer diameter.
4. Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent set ion) t=kã? core no. Ã? section (kg), in formula, the coefficient k value should be: the copper core get 7, the aluminum core get 4.
5. Allowed biggest lateral-press p, when cable is being bent
The single core cable is required pâ?¤ 500kg/m.
P=t/r (t is indicated axial traction force; r is indicated radius of bent-wheel), knowing from above formula, as the traction force is made up by length and weight of cable. So it lets p to applying requirement as above. Then the diameter of bent-wheel should be widened.
6. Cable laying is not being restricted by drop.

In the field of power transmission, high-voltage cables are an indispensable component. The selection of insulation materials for high-voltage cables is crucial for power transmission. In this paper, we will focus on the common insulation materials and their characteristics of high-voltage cables, and analyze the advantages and disadvantages of different types of insulation materials by comparing and contrasting them, and make an in-depth analysis from the perspectives of material properties and applicable scenarios.

First, let's take a look at polyvinyl chloride insulated power cables. As a common insulating material, PVC has good heat resistance and corrosion resistance, and is suitable for power transmission under various environmental conditions. The nominal thickness of its insulation can also effectively prevent current leakage and improve the safety of the cable. However, PVC insulated power cables also have some disadvantages, such as easy deterioration in high temperature environments, and need to be replaced periodically to ensure the stability of power transmission.

Another common insulating material is cross-linked polyethylene. Compared with PVC, cross-linked polyethylene has higher heat and voltage resistance and is suitable for high-voltage power transmission. Its insulating properties are stable, and it is not easy to deteriorate in long-term use, making it an excellent insulating material. However, cross-linked polyethylene is relatively expensive and needs to be selected according to specific scenarios.

When selecting insulation materials for high-voltage cables, various factors need to be considered according to the actual power transmission scenario. The properties and application scenarios of different insulating materials differ significantly, so it is crucial to choose the right insulating material. Only after a full understanding of the advantages and disadvantages of various insulating materials, and according to the specific needs to choose, can ensure the safety and stability of power transmission.

In summary, the selection of insulation materials for high-voltage cables has an important impact on power transmission, and it is crucial to choose the right insulation materials for different scenarios. Only by choosing under a professional, objective and analytical perspective can we ensure the smooth progress of power transmission. We hope that this article can help you better understand the insulation materials of high-voltage cables and provide some reference for the development of the power transmission field.
