Double Overhang Clamp

The optical cable Double overhang clamp is a kind of fitting used to support and fix optical cables, playing an important role in the overhead optical cable lines of the power and communication fields. The following is a detailed introduction for you:

It is a specially designed suspension clamp that uses two sets of suspension components. It is mainly used to hang various types of optical cables such as ADSS (All-Dielectric Self-Supporting Optical Cable) and OPGW (Optical Fiber Composite Overhead Ground Wire) on straight-line towers. It is particularly suitable for some special line environments, such as long-span rivers, high-drop valleys, heavy ice areas, etc., as well as various towers with a line corner not exceeding 60°. It can ensure the reliable operation of optical cables under conditions of large corners, high drops, and long spans.

It usually consists of inner wires, outer wires, rubber inserts, suspension splints, hanging plates, triangular connection plates, etc. Users can also configure and purchase other connection parts according to design requirements. Some double suspension clamps also include structural reinforcement strips, outer preformed wires, triangular connection plates, suspension components, connection fittings (such as U-shaped hanging rings, PS-type hanging plates), structural fasteners, etc.

Comprehensive performance: It has all the performance of a single suspension clamp and is optimized and upgraded on this basis.

High mechanical strength: Using two sets of suspension components greatly improves the mechanical strength of the clamp, enabling it to better withstand the weight of the optical cable and various external forces.

Good protection performance: The clamp has a large contact surface with the optical cable, the stress is evenly distributed, there is no stress concentration phenomenon, and at the same time, the stiffness of the optical cable at the hanging point is increased, providing good protection for the optical cable.

Safe and reliable operation: The curvature radius of the optical cable is increased, ensuring the safe and reliable operation of the optical cable under complex conditions such as large corners, high drops, and long spans.

Gripping force meets requirements: The gripping force of the clamp on the optical cable can meet 20% of the RST (rated tensile strength of the optical cable), which can well protect the safe operation of the optical cable under unbalanced loads.

Special geographical environments: Used for optical cable lines in special geographical environments such as long-span rivers, high-drop valleys, and heavy ice areas.

Specific corner towers: Suitable for various ADSS, OPGW and other optical cable lines in towers with a corner not exceeding 60°.

Parameter matching: Select the appropriate double suspension clamp according to parameters such as the span, outer diameter, and ultimate tensile strength of the ADSS or OPGW optical cable.

Quantity configuration: Generally, the quantity configuration is 1 set per tower with a line corner less than 25°. In some lines with special requirements, the configuration quantity may be adjusted according to the actual situation.
