30+ years

Our factory was found in 1992, first start with coaxial cable which was one of the biggest manufacturers in lin'an city.In year of 2001 started focusing on the production of optical cables.

30+ countries

In year of 2008, set up international sales department and sale optical fiber cable to more than 30 countries and have 18 years` rich experience to export cables .

• Mini armored layer used to decrease the outer diameter and cable weight, also convenient for laying and splice
• Cable using high property aramid yarn, increasing tension property, and fit for long distance use
• Cable using spiral metal armored layer with best crush property, and cable is very flexible and easy bend

Why Are Overhead Optical Cables Installed Lower Than Overhead Power Lines?

Full Explanation & Translation

Overhead optical fiber cables are erected at a lower elevation than overhead power lines for the following core reasons:

1.Mandatory safety layout specifications National communication engineering codes clearly stipulate that communication overhead cables must be mounted underneath power lines when sharing poles, with a minimum vertical clearance of 2.5 meters between them. High-voltage power lines carry lethal live electricity; raising optical cables above power lines would drastically increase the risk of short circuits, electric shocks and equipment burnout during construction, maintenance or accidental contact. Arranging fiber cables below power lines eliminates this major hazard.

2.Fundamental difference in electrical safety risks Power lines transmit high-voltage alternating current. Any accidental contact by people, vehicles or metal objects will cause fatal electric shock, arc flash or fire. Therefore power lines must maintain a large vertical clearance from the ground and all other facilities. Optical cables only transmit light signals and carry no live electricity; touching them poses no electrocution risk, so they can comply with much lower minimum ground height standards (3–5.5 meters for most road sections, versus 6–8+ meters for low/high-voltage power lines).

3.Distinct design purposes and load standards Overhead power lines need long-distance power transmission and must resist severe sagging under heavy current, ice and wind. They require tall, robust towers with high suspension heights to avoid ground contact. Overhead fiber cables serve local broadband access with lighter weight and smaller sag; their structural design does not demand extra vertical height.

4.Distinct safety clearance requirements against external interference High-voltage power lines generate strong electromagnetic fields and electrostatic induction. If optical cables were placed above power lines, induced voltage would damage communication equipment. Locating fiber cables below power lines, paired with standard vertical separation distances, effectively suppresses electromagnetic interference on fiber transmission signals.

5.Practical operation and maintenance logic When workers inspect or repair lines, operating on lower fiber cables avoids reaching across energized power conductors overhead, greatly reducing the chance of accidental electric shock during field work.
