In some relatively large-scale communication projects, reasonable optical fiber wiring connectors are essential. Although the shape
difference is not large, the functional difference is very obvious. In this issue, we will focus on several commonly used fiber optic
connectors, start with mutual comparison, and deeply analyze their application scenarios.
Application:
The suspension clamps are mainly used for suspending optic cable(or conductor) in overhead line, similar with ordinary suspension
clamp. When used for conductor and ground wire’s installation in ADSS cable and HV transmission line, we suggest the line corner
angle is ≤ 30° .ADSS preformed suspension clamp is mainly used to support the suspend ADSS cable. It is suitable for the ADSS cable,
conductor and grounding wire on transmission line. It is recommended used on the line with turning angle less than 30 degree.
Advantages:
ADSS preformed suspension set is applicable for connection of ADSS optical cable suspended on overhead transmission line to pole or
tower on which the clamp can both lessen static stress imposed on optical cable on the suspended point and enhance anti-vibration
capacity for optical cable through restraining wind vibration to optical cable, protecting optical cable from influence of bending stress
as well as from additional consumption.This helical suspension clamp is the connecting fitting that hangs ADSS cable onto the poles
or tower in the transfer line, the clamp can decrease the static stress of cable at hanging point, improve anti vibration capacity and
restrain dynamical stress caused from wind vibration. It also can ensure that the cable bend doesn’t exceed allowable value and cable
doesn’t generate bend stress. By installing this clamp, the various harmful stress concentrations can be avoided, so the additional
damage wastage shall not occur in the optical fiber within the cable.

Tension Guy grip for ADSS cable
Hot dip galvanized spiral dead-ends without armored rods for a direct installation on the cable for works on short spans (70 m max.);
Hot dip galvanized amored rods for a direct protection on the cable and a spiral dead-end for anchoring cables on medium spans
(150 m max.) and long spans (350 m max.).
In addition to these amored rods and this dead-end, various accessories should be ordered separately to complete to complete the pole
configuration (thimble, turnbuckle, bracket, etc.).
Application scenarios:
Terminal、 tensile 、tension joint pole/tower.
Terminal pole/tower: it is the last pole/tower in the fiber route;
Tensile pole/tower: when the pole/tower route direction change, different pull force will appear on the corner pole/tower. cables no spliced .
Tension joint pole/tower: the pole/tower is where cables will be spliced.
Range of diameter of ADSS cable:11.3±0.5mm.
Tension string failing load≥95% RTS (RTS=7 kN).
Down lead clamp for ADSS
Application scenarios:
They are generally installed on the tension joint pole/ Tensile pole middle fixed.
Every 1.5 m -2 m install 1 pc.
| Description | Qty | Clamp use for ADSS cable diameter range |
| Down lead clamp | 1 pc | 9-14.4mm |
Slack Storage Bracket on pole for cable
Cable Storage Assembly is used for storage of reserved optical fibre cable. It is divided into Inserted type storage and Outside
coil type storage, they are generally installed on the strain tower and pole.
Application
•The function of the remaining cable rack is to store the reserved optical cable, which is generally used on the tensile tower (pole).
• It is generally divided into an internal buckle type residual cable rack and an external disc type residual cable rack.
Stainless steel band and Stainless steel buckle Set
Stainless steel strap is designed to attach suspension bracket and dead end bracelet to the poles.
The material of straps and buckles can be 201 or 304 stainless steel.
The stainless strapping band is used in many industries to bind items together or to affix loose items to more stable ones.
The steel coil banding is applied with suspension clamps, anchor clamps, and hooks on dead end and international routes.
