Core strengths

Factory direct supply

Its own 50,000 square meters of modern production base, annual output of more than 50,000 tons of various power steel components, steel single column cable termination tower from raw material procurement, steel cutting, welding and forming to hot-dip galvanizing anti-corrosion.

The whole process of independent control, refusal to outsource, each steel single column cable termination tower has been strictly tested to ensure uniform specifications, stable performance, greatly reduce the cost of intermediate links, cost-effective supply, and meeting the bulk procurement needs of various power projects.

Super anti-corrosion

Adopting a high-standard hot-dip galvanizing process, the thickness of the zinc layer ≥ 85μm, far exceeding the requirements of the national standard.

The zinc-iron alloy layer is combined with the metallurgy of the steel matrix, the adhesion is extremely strong, not easy to fall off, not rust, can effectively resist coastal salt spray, high temperature humidity, industrial corrosion and other complex environmental erosion.

In the ordinary environment anti-corrosion life of more than 30 years, greatly reduce the maintenance cost of the whole life cycle of steel single-column cable termination towers.

Safety and reliability

the selection of high-strength steel, after precision welding and forming process, the weld seam is full and uniform, without flaws, the wind resistance level is ≥ 12, the overturning coefficient is ≥ 1.5.

The bottom flange and stiffener plate reinforcement design, the bearing capacity is strong, it can stably support cable termination heads, lightning arresters and other equipment, adapt to the needs of high-voltage and ultra-high-voltage power transmission, and prevent the deformation and dumping of steel single-column cable termination towers caused by extreme weather or equipment load, so as to ensure the safety of power transmission.

Flexible customization and wide adaptation

According to the voltage level, transmission capacity, and installation scenarios of power engineering, steel single-column cable termination towers with different heights, pipe diameters, and wall thicknesses can be customized to meet various voltage levels such as 110KV and 220KV.

It can be applied to different scenarios such as urban main roads, industrial parks, along highways, and around bridges, and at the same time support the integration of OPGW optical cables, monitoring equipment and other functions to meet diverse power transmission supporting needs.

Compact footprint and convenient construction

Compared with traditional transmission towers, steel single-column cable termination towers have a compact structure and small footprint, only about 1/3 of the area occupied by traditional towers.

The prefabricated production of rods and on-site installation do not require complex tower assembly processes, which can greatly shorten the construction period, improve construction efficiency and reduce construction costs.

How the product works

As a key connection equipment in the power transmission system, the core role of the steel single-column cable termination tower is to realize the safe connection and power conversion between overhead lines and cable lines, and its working principle revolves around the stability and safety of power transmission.

First of all, the steel single-column cable termination tower is firmly connected to the ground through the bottom fixed foundation, a stable support platform is built, and the cable termination bracket is installed in the designated position of the tower.

Secondly, through the insulation support leads, the underground cable and the overhead line are accurately connected to achieve the smooth transmission of power from the cable to the overhead line, or from the overhead line to the cable, and at the same time bear the tension between the cable and the overhead wire, ensure that the wire maintains a safe distance from the ground and other objects, and prevent potential safety hazards such as current leakage and short circuit.

In addition, steel single-column cable termination towers can effectively protect cable terminations, lightning arresters and other equipment, resist external environmental influences such as wind and rain, lightning, corrosion, etc., ensure the stability and efficiency of the power transmission process, and provide core support for the safe operation of the power system.
