10kV overhead insulated cable

1. Product name: 10kV overhead insulated cable

2. Executive standard: GB/T 14049-2008

3. Product introduction: Overhead cable (full name overhead insulated cable) is an overhead wire equipped with an insulating layer and protective sheath, and a special cable is manufactured by a special cable similar to the production process of cross-linked cable, which is a new power transmission mode between overhead wire and underground cable. Overhead cables are all single-core, which can be divided into duralumin wire structure, hard-drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core support structure and self-supporting three-core textured structure (wire core can be duralumin or hard copper wire) according to their different structures.

4. Product advantages: 1. The long-term maximum conductor working temperature of the product is 90 °C, the minimum laying temperature is -20 °C, and the maximum short-circuit temperature of 5S is 250 °C. 2. This product has simple structure, short manufacturing cycle, easy installation and maintenance, and has the main characteristics of high power supply reliability, good power supply safety, convenient erection and maintenance, and reasonable economy.

5. Applicable places: It is suitable for large-span overhead fixed laying as the purpose of power transmission and distribution, and can also be used for transformer down wire, and is not limited by drop when laying.
