04-SINGLE SUSPENSION ENVELOP TYPE- PIPE ARCING HORN LINE SIDE - WITHOUT ARMOUR ROD

MMPT have created an identifiable position in the market by manufacturing and supplying superior quality Suspension Hardware.
The main purpose of this hardware is to hang the conductor/cable to the insulator. The clamps help to link all other fittings and accessories to the tower arms. It promotes safety of the conductor/cable and people by preventing voltage leakage. It enchance the stability of the conductor by limiting their movement, especially against a strong wind, storms and other natural calamities.

Suspension Clamps (Envelope Type) are flexible and moveable along the axis of the conductors only and provide minimum power loss. These type of Clamps are very commonly used in sub-stations.
The clamp body and pressure plate of envolope-type overhanging clamp are made of high-strength aluminium alloy.Traditional cast iron clamps have the disadvantages as large current loss is there, and they are bulky/heavy compared to envelope type suspension clamps.

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 provide a path for flashover to occur that bypasses the surface of the protected device. Horns are normally paired on either side of an insulator, one connected to the high voltage part and the other to ground, or at the breaking point of a switch contact.

MMPT Envelope type suspension hardware can be custom manufactured with different wire numbers, a wide range of cable sizes, wire raw material.
