Preformed fittings
Introducton for suspension clamp:
Armor Rods are intended to protect against bending,compression, abrasion, arc-over whilst also being capable of providing a repair function. The degree of protection needed on a specific line depends upon a number of factors such as line design, temperature, tension, exposure to wind flow and vibration history on a similar construction in the same area.
Armor rods are recommended as a minimum protection for clamp type supports or suspension. Armor Rods can be used to restore full conductance and strength to AAC, AAAC and ACSR conductors.
Preformed tension clamps are used for the installation of bare wires or overhead insulated wires of transmission and distribution lines. It can replace the traditional bolted type and hydraulic tension clamp. Its structure is simple. After installation, the tubular structure formed by the preformed wire legs is naturally wound on the wire to produce a strong grip. The grip strength of the clamp is not less than calculate the breaking force of 95% stranded wire; the stress distribution of the wire clip to the wire is even, without damaging the wire, improving the vibration resistance of the wire and greatly extending the service life of the wire.
The preformed armor rods is used to protect the conductor from vibration, compressive stress of the clamp, friction and wear, arc and other damages. It is usually installed in the boat-type suspension clamp and the insulation of the pillar to increase the rigidity of the conductor and reduce the conductor at the outlet of the clamp. Its structure is simple. The main function of preformed armor rods is to evenly distribute the concentrated stress, which not only improves the resistance of the wire to vibration, but also extends the service life of the wire. It can be installed by hand without the need to carry tools. The quality is also easy to guarantee, and the naked eye can be tested. The appearance is generally considered to be beautiful.
