DOUBLE SUSPENSION ENVELOP TYPE- WITH ARMOUR ROD

MMPT have created an identifiable position in the market by manufacturing and supplying superior quality Suspension Hardware.
Double Suspension Hardware Fittings are installed where double strings of insulators are being used.
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.

Armor rods are designed to protect cables from bending, compression, abrasion and flash-over. it can also be used in repairing damaged aluminium-based conductors and restore the mechanical strength of the conductor and conductivity of the conductor.The raw materials of the armor rod are aluminium wire, galvanized steel wire, and aluminium clad steel wire. The armour rod material should be similar to the conductor surface material, avoiding corrosion between different elements.

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