6-35KV overhead insulated cable Global Procurement Guide
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 conductor with insulating layer and protective sheath. It is a special cable manufactured by a production process similar to cross-linked cable. It is a new power transmission mode between overhead conductor and underground cable. Overhead cables are single core. According to their different structures, they can be divided into 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 (the wire core can be hard aluminum or hard copper wire), etc.

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. The 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 place: it is suitable for overhead fixed laying with large span for energy transmission and distribution. It can also be used for transformer downlead, and the laying is not limited by the drop.

6-35KV overhead insulated cable FAQ

What is the maximum operating temperature for 6-35KV overhead insulated cables?
The standard maximum operating temperature is typically 90°C for XLPE-insulated cables, with short-circuit ratings up to 250°C.
What types of insulation materials are used in these cables?
Common insulation materials include XLPE (Cross-Linked Polyethylene) and HDPE (High-Density Polyethylene), offering high dielectric strength and weather resistance.
Are these cables suitable for high UV exposure environments?
Yes, they are designed with UV-resistant outer layers to withstand prolonged sunlight exposure without degradation.
What is the typical service life of 6-35KV overhead insulated cables?
Under normal conditions, the expected service life is 25-30 years, depending on environmental factors and maintenance.
Do these cables require additional support structures when installed overhead?
Yes, they should be supported by weather-resistant clamps, poles, or messenger wires to prevent sagging and mechanical stress.
Can these cables be installed in areas with high wind or ice loads?
Yes, they are designed to endure high mechanical stress, but proper tensioning and spacing are necessary for extreme conditions.
What are the key advantages of using insulated overhead cables instead of bare conductors?
Benefits include reduced risk of short circuits, improved safety, lower maintenance, and better resistance to environmental factors.
How are faults detected in 6-35KV overhead insulated cables?
Faults can be detected using insulation resistance testers, partial discharge monitoring, or thermal imaging cameras.
Are these cables compatible with existing overhead power line infrastructure?
Yes, they can often replace bare conductors without major modifications, but proper clearance and tension adjustments may be needed.
What international standards apply to 6-35KV overhead insulated cables?
Common standards include IEC 60502, IEEE 525, and GB/T 12527, ensuring compliance with electrical and mechanical performance requirements.
