110kv Composite Insulator Double-Conductor Tension String Hardware

110kv Composite Insulator Double-Conductor Tension String Hardware

110kV composite insulator double-conductor tension string hardware is specifically designed to support and anchor bundled or twin conductors on high-voltage transmission lines. These hardware assemblies combine polymer tension insulators with precision-engineered metal fittings to withstand high tensile loads, pollution conditions, and dynamic mechanical forces. They are used at strain towers, angle towers, long spans, twin-conductor sections, and high-load locations on 110kV transmission lines. Nooa Electric designs and manufactures these assemblies to meet IEC and utility-specific requirements for mechanical strength and insulation performance.

110kV composite insulator double-conductor tension strings are used on transmission lines where twin-bundle conductors are required to increase current-carrying capacity and reduce corona. The system includes polymer tension insulators arranged in one or two parallel strings, combined with double-conductor tension clamps, yoke plates, and ball-and-socket metal fittings.

Applications of 110kV Double-Conductor Tension String Hardware

Used at strain towers, angle towers, long spans, twin-conductor sections, and high-load locations on 110kV transmission lines.

These systems are commonly used in:

110kV twin-bundle transmission lines

Strain/anchor towers for double conductors

Angle towers with high mechanical load requirements

Long-span crossings (rivers, valleys, mountains)

High-wind or ice-load regions
Coastal and polluted environments

FAQ: 110kV Composite Insulator Double-Conductor Tension String Hardware

1. Does a double-conductor tension string require special clamps?

Yes. Double-conductor tension clamps are designed to grip two conductors simultaneously and distribute tension evenly.


2. Do composite tension strings require corona or grading rings?

Often yes—especially in areas with high EMF or contamination.


3. Are composite insulators suitable for cold or hot climates?

Yes. Silicone rubber maintains performance in −40°C to +55°C environments.


4. Can Nooa Electric design customized twin-conductor fittings?
Absolutely. Nooa Electric provides custom clamps, yoke plates, and string configurations based on line design drawings.
