Double Tension Compression hardware with both side pipe type arcing horn

MM Powerline Transmission is one of the leading manufacturer and supplier of Double Tension Compression Hardware.
Arcing horns (Pipe Type)are projecting conductors used to protect insulators or switch hardware on high voltage electric power transmission systems from damage during lightning strikes and other overvoltage phenomena.

Arcing horns are projecting conductors used to protect insulators or switch hardware on high voltage electric power transmission systems from damage during lightning strikes and other overvoltage phenomena.

The Arcing horns(Pipe Type)comprise a pair of pipe having V-shaped outer ends criss crossing one another along one lateral side of the insulator and arranged to form multiple self-extinguishing wiring gaps emanating from the common gap between the spaced apart apexes thereof. The assembly is eminently suited for installation vertically, horizontally or in an inclined position. The hardware components are identical and integral except for fasteners.

Double Tension Compression Hardware can be used for Overhead Lines and Substations and can achieve the highest breaking load,using Compression connection techniques.

Compression Hardware ensures proper connection/fitting. It helps in reducing power loss, hence increasing the electrical conductivity. These are rust free, having longer life than Bolted type, and are light in weight.
In case of any fault/damage, only the damaged portion is required to change.

Double Tension Compression Hardware are applied where double strings of insulators are used.
Double Tension Compression Hardware are easy to install.
