Types of optical cable fittings?
Optical fiber fittings mainly include: suspension clamps, tension clamps (also known as static end components), connecting fittings, anti-vibration fittings, downlead fixing fittings, and remaining cable racks .
Technical requirements?
Fittings must be designed and developed based on the characteristics of optical fiber. In addition to meeting the technical requirements of general power fittings, optical fiber fittings should also consider: The extrusion force of optical cable fittings should not exceed the requirements. ?The design extrusion limit. Fittings are generally not suitable to be designed to suit a range of diameters. One type of fittings must correspond to one specification and diameter. ?
Optical cable fittings should disperse the stress so that it does not exceed the allowable bending stress and do not cause local pressure to damage the cable core during installation. ?
Wear, wind vibration, dancing, torsion and other factors should also be considered when designing. The installation of optical cables on power towers must be completed with special optical cable installation hardware. Different towers, different spans, and different outer diameters use different hardware. If the hardware is improperly selected, serious accidents such as loosening of the optical cable or fiber breakage may occur. .

Optical cable hardware configuration:
The optical cable installation hardware includes fastening clamps, tension clamps, suspension clamps, down-lead clamps, joint boxes, spiral dampers and residual cables Frames, respectively, are expressed as follows:

Tension Clamps
Used on terminal towers and line intermediate tension towers, it can evenly distribute radial pressure and transmit axial tension. It provides safe and reliable gripping force without damaging the optical cable. Its main technical parameters are the breaking force of the cable clamp () and the cable diameter range (). The basic configuration is the terminal tower cover and the tension tower cover in the middle of the line. Fiber Cable Tension Clamps securely and gently secure all-dielectric self-supporting aerial fiber optic cables. The structural reinforcement lines transmit axial tension and distribute radial pressure to the clamp assembly, thereby ensuring maximum gripping force without causing damage to the cable sheath and deformation of the optical fiber. Baoding Henglida Line Equipment Co., Ltd. provides three types of tension clamps: low tension, medium tension and high tension.
Suspension cable clamps
It is mainly used on linear towers. It is a connecting hardware for suspending optical cables on the tower. It is used to protect the optical cables from damage during erection and operation. Its main technical parameters are cable clamps Breaking force () and cable diameter (), the basic configuration is a set on each linear tower. Depending on the application and the brand of optical cable, Baoding Henglida Line Equipment Co., Ltd. provides three types of suspension clamps: low tension, medium tension and high tension.
Down lead clamp
It is to fix the optical cable led from the tower to the tower to prevent it from shaking to avoid wearing the surface of the optical cable. It is mainly used at the terminal tower and connecting tower of the optical cable line. Its main purpose The technical parameter is cable diameter (), which is generally matched with each.
The spiral damper
is an interference type damping device that uses its damping part to dampen wind vibration and consume the vibration energy generated by the wind when the optical cable is running. To prevent damage to hardware and optical cables due to vibration, the main technical parameters are the gripping force of the spiral shock absorber () and the cable diameter range (). Its configuration is determined according to the size of the optical cable line spacing. Generally, the following spacings are not used, and ~ Duangen.
The remaining cable rack
is used to coil the excess optical cables on the tower. Its main technical parameter is the diameter of the remaining cable rack (). It is usually used in conjunction with the optical cable splice box. Each setting The connection box is equipped with a cable rack.
Connector boxes for optical cables
, connector boxes for towers, connector boxes for poles
Purpose: Used for intermediate connection and branch protection of optical cable lines, which can be used for sealing, protective placement The function of optical fiber connectors and reserved optical fibers for storage protects them from the influence of external environmental factors.
The fastening clamp
is used to connect tension clamps, suspension clamps, residual cable racks and optical cable splice boxes to the tower. Its main technical parameters are failure load () and optical cable hanging The size of the main material of the power tower at the point position is configured in a one-to-one correspondence with the tension clamps, suspension clamps, remaining cable racks and optical cable splice boxes.
