Generally , optical cables are equipped with matching hardware during construction. For ADSS optical cables, the matching hardware mainly includes tension clamps, suspension clamps, down conductor clamps, fastening clamps, shockproof hardware, junction boxes, etc. Due to line spacing, construction environment and other conditions, the hardware will be different. Below YINGDA of the use of several common matching hardware for ADSS optical cables.

ADSS optical cable fittings installation  diagram

1. Variable diameter pole hoop

Application: Primarily used for installing tension and suspension clamps for ADSS optical cables on pole-mounted lines (hanging points).

A. Pole Hanging Point Clamp

Application: Mainly used for securing cable supports on pole-type lines.

B. Special clamp for cable storage

2.Preformed strain sets/dead end

Application: ADSS preformed dead end are mainly used for fixing and anchoring overhead self-supporting ADSS optical cable lines. They are generally installed on terminal towers, tension towers, corner towers, etc.

Composition: Each set of pre-twisted wire tension clamp assembly includes: inner twisted wire, outer twisted wire, and pull ring. ADSS optical cable users can configure and purchase other connectors according to design requirements.

Features: The gripping force of the pre-twisted wire tension clamp on the conductor (optical cable) can reach more than 95% of the ultimate tensile strength (R.T.S) of the conductor (optical cable), without the influence of stress concentration and vibration stress.

3.ADSS suspenstion clamp

Application: The ADSS dead end is primarily used for suspending cables on overhead, self-supporting ADSS optical cable lines, similar to conventional suspension clamps. It is recommended for use in environments with line angles ≤ 30°.

Features:

1. Its extremely low static stress distribution improves its ability to withstand dynamic stresses (such as vibration or dancing). Its gripping force for ADSS optical cables can reach 10% to 20% of the cable's ultimate tensile strength (RTS).

2. It provides a flexible grip without rigid contact with the cable, minimizing wear.

3. Its high-quality material ensures excellent elasticity and toughness, strong fatigue resistance, and corrosion resistance, ensuring a long and safe service life.

4. It not only effectively protects the optical cable, but its smooth profile significantly reduces corona discharge and electromagnetic losses.

Components: The pre-twisted wire suspension clamp consists of inner and outer twisted wires, a rubber insert, and a suspension clamp (housing).

4. Down lead clamp

Purpose: Down lead clamps are primarily used for securing ADSS and OPGW optical cables during installation on poles and towers. For example, they secure the cable from the clamping fixture to the splice protection box at the cable splice pole (tower); they also secure the cable from the pole tower to underground pipelines, cable trenches, direct burial sites, and equipment rooms. This prevents wind damage to the cable from rubbing against the pole tower or other objects, protecting the ADSS cable. We offer the following types of downlead clamps: tower-mounted and pole-mounted.

5. Vibration Damper

Application: This anti-vibration hammer is primarily used on ADSS (Advanced Sub-Stationary Sub-Station) optical cables, OPGW (Optical Grid Wiring) cables, and overhead power lines. It eliminates or reduces vibrations caused by laminar wind flow, thereby preventing damage to the clamping hardware and the cable.

Features: The anti-vibration hammer utilizes a Haro-type design with a slotted center between the large and small hammer heads, leaving the connection between the strand and hammer head exposed. This allows for monitoring strand fatigue damage on ADSS cables without restricting hammer head swing or abrading the strands. Multiple resonant frequencies can be achieved. It is suitable for optical cables with diameters of 9.5mm to 27mm (including the cable diameter that can be clamped, including the sheathing).

Composition: The strands connected to the hammer head are refined steel strands, and the sheathing is aluminum alloy. The streamlined design effectively controls corona.

6. Cable storage frame

 Application: Mainly used for winding excess optical cables on splicing towers, usually used in conjunction with splicing boxes.

7. Metal splice box for optical cable pole

Applications: Widely used for ADSS, OPGW, and other special optical cable splices, as well as for protecting cable splices at junctions.

Features: 1. The metal splice closure is cast from an aluminum alloy, making it particularly suitable for protecting optical cable splices in high-voltage electrical fields.

2. The metal splice closure overcomes the shortcomings of plastic splice closures, which suffer from poor aging resistance and a short lifespan in electromagnetic fields, boasting a lifespan of over 25 years.

3. Cast from an aluminum alloy, it possesses excellent mechanical properties. It is far superior to non-metallic splice closures in terms of shotgun protection, contamination resistance, extreme temperature tolerance, and waterproof sealing for ADSS optical cables.

4. The metal splice closure eliminates the drawbacks of traditional cable encapsulation methods, avoiding the potential for heat encapsulation that can degrade the cable sheath and potentially damage it.

5. Available in two-, three-, and four-port configurations.

6. Multiple seals ensure excellent waterproofing.

7. The box body has a spacious structure, the fusion splice tray adopts superposition type, flexible configuration and simple installation. The bending radius of ADSS optical cable fully meets the international standard. The bottom of the optical cable joint box is designed with a certain space for coiling the remaining optical fiber, and the optical fiber has no attenuation change in the joint box.
