Preformed Helical Suspension Clamp is a common hardware for hanging optical cables on transmission line towers, and it plays an important role all the time. Preformed Helical Suspension Clamp is mainly used for connecting optical cables with straight towers or towers with an angle of less than 25°, one set for each tower. The wire clamp can reduce the static stress of the optical cable at the suspension point, improve the vibration resistance of the optical cable, and overcome the dynamic stress of wind vibration; it can also ensure that the bending of the optical cable does not exceed the allowed value, so as not to generate bending stress, thus ensuring that the optical fiber will not be lost.

The suspension clamp is mainly used for overhead power lines or substations. The conductor and lightning conductor are suspended on the insulator or the lightning conductor is suspended on the tower through the connection hardware. It can also be used to support the transposition conductor on the transposition tower and fix the non-linear tower jumper. The suspension clamp is used to suspend or support the conductor, and is mainly a hardware that bears vertical loads.

From the cast iron clamps in the 19th century to the ship-shaped clamps in the 20th century, the evolution of power fittings stagnated for half a century. It was not until the emergence of preformed suspension clamps that the original way of hanging wires truly entered a new era.

In the field of power transmission,preformed suspension clamps are key components to ensure the safe and stable operation of transmission lines, and their quality is directly related to the long-term performance of the power grid. Our company always adheres to the concept of "quality first" and ensures that every preformed suspension clamp meets industry standards by building a scientific and complete quality assurance monitoring system. We cover the whole process quality control of raw materials, production processes, and finished product testing. In the raw material link, we use high-strength aluminum alloy and stainless steel raw materials to ensure the tensile strength of the materials, and verify the corrosion resistance through salt spray tests.

Do you know? Under the dual pressure of increasing global electricity demand and carbon neutrality goals, what kind of technology can simultaneously improve grid reliability and promote green development? The preformed suspension clamp provides the answer. Why can this product improve? Why does it break the problem of conductor protection and become a benchmark for sustainable development in the power industry? The core technology of the pre-twisted spiral suspension wire clamp is mainly reflected in the following three aspects: compatibility, durability and functionality.

The use of suspension clamps can well protect the optical cable, assist in vibration reduction, and extend the service life of the line. The whole set of suspension clamps consists of: inner preformed armor rods, outer preformed armor rods, housing and rubber pads, U-shaped strap, aluminum casting, bolts, nuts, closed pins and other matching connection hardware. Different types of optical cables have different requirements for vertical clamps. Optical cables can be divided into OPGW optical cables, ADSS optical cables, OPPC optical cables and ordinary overhead optical cables.
