Product Description
Our factory produces single-core electrical overhead lines. Depending on the structure, they can be categorized into hard aluminum wire structure, hard-drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core supported structure, and self-supporting three-core composite structure, etc. Thanks to the robust materials used, our electrical overhead lines feature high power supply reliability, good power supply safety, convenient installation and maintenance, and reasonable economic efficiency, and are widely used in transmission lines abroad.

Product Feature And Application
1. Rated voltage of 1KV and below.
2. Long-term allowable operating temperature of conductor: For high-density polyethylene insulated overhead cables with a rated voltage of 1KV, the temperature should not exceed 70℃; for cross-linked polyethylene insulated overhead cables, the temperature should not exceed 90℃.
3. The laying temperature of overhead cables should not be lower than -20℃.
4. Allowable bending radius of overhead cables: For overhead cables with an outer diameter (D) less than 25mm, the radius should not be less than 4D; for overhead cables with an outer diameter (D) of 25mm and above, the radius should not be less than 6D.

FAQ
Q: How to order electrical overhead line?
A: First, clarify your procurement needs. Determine the cable type based on the project's voltage level, laying environment, and communication bandwidth. This includes specifying the cable type, core count, and specifications, while also ensuring compliance with industry standards.
Second, select suppliers. Prioritize companies with power fiber optic cable production qualifications and a track record of similar projects. Hualun Cable is a good choice; all products have testing reports, extensive engineering experience, and timely and comprehensive after-sales service. Next, conduct business negotiations to confirm product pricing, delivery time, and technical support terms, sign a formal purchase contract, and clarify acceptance standards.
Finally, upon arrival, conduct on-site sampling inspections. Verify product quality through OTDR testing for fiber attenuation and tensile strength tests. Only after passing these tests can the cable be used for installation.
