ADSS power optical cable tensile fittings
Release Date: 2022-07-16

ADSS power optical cable tension fittings are used for the connection between optical cables and towers in ADSS line erection. It is mainly used for connection with terminal towers, tensile towers, towers with a turning angle greater than 25° and connection towers.

ADSS power optical cable tensile fittings

product description:

1. The product is used for the connection of optical cable and tower in ADSS line erection. It is mainly used for connection with terminal towers, tensile towers, towers with a turning angle greater than 25° and connection towers.

The specific configuration is: 1 set of terminal towers/tower; 2 sets/tower of tensile towers, continuous towers, and towers with a turning angle (elevation angle) greater than 25°.

2. The user selects a suitable tension clamp according to the cable diameter, cable tensile strength or span.

3. The complete set of wire clips includes: one set of inner protective wire pre-twisted wire, one set of outer layer of tensile pre-twisted wire, one set of heart-shaped ring, one set of hanging plate and two sets of U-shaped hanging ring.

Product Usage:

Under full tension. Connect ADSS fiber optic cables to terminals, tensile (angles greater than 25°) or fiber optic splice towers.

product structure:

1. Pre-twisted wire of inner protective wire: It is made of aluminum-clad steel wire.

to increase the friction with the cable. The end of the pre-twisted wire is bent to the outside to avoid crushing damage to the cable.

2. Outer tension pre-twisted wire: The pre-twisted wire is made of aluminum-clad steel wire layer, and the pre-twisted wire is made into a bundle, and white corundum emery is glued to the inner wall.

The tensile strength of the tensile clamp has been increased under the condition of reducing the stress on the optical cable.

3. Heart ring: hot-dip galvanized precision casting.

The breaking loads are 50KN, 70KN, 100KN and 120KN.

4. Hanging plate: hot-dip galvanized steel, the function of linking heart like and U-ring.

The breaking loads are 50KN, 70KN, 100KN and 120KN.

U-shaped hanger: hot-dip galvanized steel U-shaped hanger, which plays the role of connecting with the pole and tower fasteners.

Common specifications: U-5 (50KN), U-7 (70KN), U-10 (100KN), U-12 (120KN) four


1. The outer stranded wire is directly connected to the tower through the connecting fittings such as the insert ring to bear the line load.

2. Structural reinforcement bars have a certain protective effect on the ADSS optical cable. As a force transmission unit, the main functions are:

(1) Effectively transmit the longitudinal compression force to the tension bearing unit of the optical cable → aramid, so as to prevent the outer sheath of the optical cable from being stretched due to excessive force.

(2) Transmit axial tension.

(3) The contact area with the optical cable is increased, so that the stress distribution is uniform and there is no stress concentration point.

3. Under the premise of not exceeding the lateral pressure strength of the ADSS optical cable, it has a large holding force for the optical cable and can withstand a large tension.

4. The holding force of ADSS optical cable is not less than 95% of the ultimate tensile strength (UTS) of the optical cable, which is completely suitable for the needs of optical cable erection.

Order Notice:

1. According to the ultimate tensile strength, running distance and outer diameter of ADSS optical cable, select the appropriate tension clamp.

2. The relevant parameters of the ADSS optical cable should be provided at the same time: the allowable tension of the optical cable, the daily operating tension and the lateral compression strength. If it is a single glue, the glue direction should be provided.

3. Quantity configuration: 1 set/terminal tower; 2 sets/tensile tower, the turning angle is greater than 25° and the ADSS optical cable connection tower.

4. After the tension clamp is under full tension, it is recommended to use it once.
