Down Lead Clamp

Down Lead Clamp Introduction

Down Lead Clamp is used for fixation of OPGW and ADSS onto the pole /tower. The down lead clamp is suitable for the cable diameters requested by clients. The installation is reliable, convenient, and fast.Down Lead Clamp is divided into two basic types: pole used and tower used. Each basic type is divided into electro-insulating rubber and metal types. Electro-insulating rubber-type Down Lead Clamp is generally used for ADSS installation, while metal-type Down Lead Clamp is generally used for OPGW installation

Features & Advantages: 

• Simple and practical structure

• Convenient installation and fastening

• Steel components are made of steel, HDG

• The downlead for tower could be adjusted 90°in direction

• Easy to install

• The adjustable range is wide

• Applicable to the different thickness towers

Installation of downlead clamp, cable tray and joint box

Cable at the splicing point on the tower should be spliced after being lead to the ground. Along two sides of earth wire stand of the tower to the tower body and then lead along the inside of the tower body.

Bending radius of the route where downlead passes through shouldn't be less than 1m, and the minimum bending radius should be promised during operation, generally more than 0.5m.

After the cable is lead to the ground, downlead clamp is used to fasten the cable on principle material or other material of the cable. Anchor ear type downlead clamp should be used when it is lead along concrete pole (such as converting station, power plant structure).

Cable downlead should be straight and beautiful.

Joint box and cable tray should be installed at suitable place on the tower, and about 8~10m above the datum surface of the tower. The installation should be firm and all the lines should be unified.
