3、 Product Introduction: Overhead Cable (also known as Overhead Insulated Cable) is an overhead conductor equipped with an insulation layer and a protective sheath. It is a specialized cable manufactured using a production process similar to cross-linked cables, and is a new transmission method between overhead conductors and underground cables. Overhead cables are all single core and can be divided into different structures such as hard aluminum wire structure, hard drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core support structure, and self-supporting three core corrugated structure (wire core can be hard aluminum or hard copper wire).

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

5、 Applicable location: Suitable for fixed overhead installation with large spans for power transmission and distribution, and can also be used for transformer down conductors, without being limited by drop height during installation.
