Cable engineering refers to the construction process of laying cables and wires in fields such as power engineering, communication engineering, and construction engineering. There are mainly various cable laying methods, including cable laying, installation in cable trays, laying in cable trenches, through pipelines, and in cable trays, etc. For different cable laying construction environments and methods, different equipment is required to assist in the construction to improve construction efficiency and ensure construction quality.

What is the common cable laying equipments

The cable reel and cable reel support

It is mainly used to place and rotate the cable reel. During cable laying, it reduces the traction tension and avoids cable damage caused by excessive dragging. The models include 3T cable pay-off racks, 5T cable pay-off racks, 10T cable pay-off racks, 15T cable reel shaft supports, 20T cable reel supports, and cable reel pay-off supports with even larger tonnages. The applicable diameter range of cable reels for the cable reel supports is 600mm – 3800mm. Users can select appropriate cable pay-off racks according to the diameter and tonnage of the cable reels.

Cable conveyor

The cable conveyor is an electric machine used for laying power cables (or communication cables). It is used in conjunction with traction equipment such as winches and hoists to overcome huge frictional forces and reduce damage to the cables. The cable conveyor is suitable for large-scale renovation of urban power grids, and is suitable for laying cables with large cross-sections and over long distances. It reduces labor intensity and improves the construction quality. The cable conveyor has a large thrust, a small volume, a light weight, and is easy to operate. It is particularly suitable for situations such as cable laying in conduits, in tunnels, direct burial, and long-distance transportation.

The types of cable conveyors are divided into diesel cable conveyors, gasoline cable conveyors, and electric cable conveyors. Because these cable conveyors can be remotely controlled, steplessly speed-regulated, and used in series, they can achieve large-scale and long-distance transportation projects of large cables. At the cable laying construction site, the appropriate model can be selected according to the diameter of the cable to be conveyed and whether the power source can be provided on site.

Cable winch

The engine-powered cable winch is the most important construction equipment for cable laying, mainly used for pulling, dragging cables and wires. It has the advantages of reasonable structure, small size, light weight, high power, flexible operation, and convenient handling, and is deeply loved by cable laying practitioners. When the engine-powered winch is used in combination with power auxiliary materials such as cable mesh sleeves and traction ropes, it can lift and pull under various complex conditions, quickly and safely drag cables, and improve work efficiency. Generally, the electric winch can be remotely controlled and has stepless speed regulation, making the operation more intelligent. The gasoline or diesel winch is more suitable for places without electricity in the wild, which is simple and convenient.

Cable rollers& cable tray

There are various types, including straight-line pulleys, corner pulleys, wellhead pulleys, etc. Straight-line pulleys are used to support the cable, reducing the friction between the cable and the ground or other objects; corner pulleys are used to change the laying direction of the cable; wellhead pulleys are used to guide the cable at special positions such as when the cable enters and exits the wellhead, protecting the outer sheath of the cable from damage.

Generator

When there is no power supply in your cable installaion project site,then you need a generator to provide power for cable conveyor and cable winch.

Cable protectors and wire ropes

Conclusion

In practical applications, diesel/gasoline cable conveyors become the first choice for field operations due to their portability, while electric models adapt to complex urban environments with features such as remote control and stepless speed regulation. The tracked integrated cable laying platform, through designs like master-slave winch synchronization and automatic steel wire rope retraction, improves cable pulling efficiency by 20% and reduces labor requirements by 50%. Additionally, the combined application of cable tractors and tension meters can precisely control cable tension, avoiding insulation damage caused by overload.
