Project Background In long-distance power cable installation projects, contractors often face difficulties in controlling cable pulling force, side pressure and synchronization between multiple cable laying machines. Traditional cable laying work depends heavily on manual operation, which may lead to unstable pulling speed, cable damage and low installation efficiency. To solve these problems, we provide an Intelligent Cable Laying System integrating cable conveyors, traction control, side pressure control, electric drum control, camera monitoring and RS485 central communication. Customer Pain Points During power cable laying projects, the customer may face the following problems: Unsynchronized equipment operationMultiple cable conveyors and pulling devices are difficult to control at the same time. Excessive cable pulling forceIf the traction force is not monitored properly, the cable may be stretched or damaged. High side pressure at turning pointsCable bending areas may generate high side pressure, increasing the risk of cable sheath damage. Low construction efficiencyManual communication and separate machine control slow down the whole cable laying process. Limited site visibilityOperators cannot easily monitor each machine position during long-distance cable installation. Solution The intelligent cable laying system adopts a centralized control design. Each key device is equipped with a control box and connected through RS485 wired communication. The system can integrate: Intelligent laying platform Intelligent cable conveyor Side pressure control system Traction control system Electric drum Camera monitoring Central control platform RS485 communication network Twisted-pair cable for control and data transmission This structure allows operators to monitor and control the whole cable laying process from one central platform. System Architecture The system uses RS485 communication to connect different cable laying devices. Each machine has its own control box, and all devices are linked to the intelligent laying system central control platform. The camera system can assist site monitoring, while the traction control and side pressure control units help protect the cable during installation. This design is especially suitable for power cable laying projects where several conveyors, rollers and pulling devices need to work together. How It Works The electric drum releases the cable steadily. The cable conveyor pushes the cable forward along the laying route. The traction control system monitors pulling force. The side pressure control system helps protect the cable at bending or turning areas. Each unit communicates through RS485 wired communication. The central control platform monitors and coordinates the whole cable laying process. Cameras provide visual assistance for site operation and safety checking. Benefits for Cable Laying Projects 1. Synchronized Cable Laying The RS485 communication system allows multiple machines to work together, reducing the risk of speed mismatch between conveyors and pulling devices. 2. Better Cable Protection By controlling traction force and side pressure, the system helps reduce cable sheath damage, excessive stretching and installation risk. 3. Higher Construction Efficiency Operators can manage the laying platform, conveyor, traction unit and electric drum from a central control platform, reducing manual coordination work. 4. Safer Site Operation Camera monitoring and centralized control help operators observe the working condition of each device during cable installation. 5. Suitable for Complex Power Projects The system is suitable for long-distance power cable laying, underground cable installation, tunnel cable construction and utility power projects.

The pulleys are used for triple-bundled conductor stringing on a new high-voltage transmission line. After several sections of the line were completed, the customer reported that the pulleys ran smoothly, protected the conductors well, and helped improve overall stringing efficiency. Transmission line construction in Thailand has its own characteristics and challenges. Many lines pass through mountainous terrain, forests and agricultural areas, involving frequent crossings over roads, rivers and farmland. At the same time, the tropical climate brings high humidity and frequent rainfall, which puts higher demands on the corrosion resistance and bearing sealing of stringing blocks. With the increasing use of triple-bundled conductors, any mismatch between pulley design and conductor size can easily lead to surface scratches, twisting, or local stress concentration on the conductor. After studying the conductor size, bundle spacing and crossing conditions of the project, we recommended the Triple Stringing Pulley SHSQN320X60(S) for this Thai contractor: The triple-sheave design is specially suited for triple-bundled conductor stringing, helping keep each subconductor under similar tension and reducing the risk of twisting or entanglement. Each pulley is equipped with 320*60 mm nylon sheaves, with a smooth groove profile and adequate strength. This structure provides a good balance between mechanical strength and surface protection, effectively reducing conductor scratches and dents during passage. The pulley frame uses a reinforced side-plate structure and high-quality rotation bearings, designed to cope with Thailand’s high-temperature, high-humidity and long-duration operation requirements. The SHSQN320X60(S) can be easily integrated into the customer’s existing stringing equipment set, including their current stringing pulley blocks, hydraulic cable pullers and tensioners, ensuring convenient installation and good compatibility on site. During field operation, the site engineers observed that, compared with their older pulley models, the Triple Stringing Pulley SHSQN320X60(S) delivered much better performance in terms of rotation smoothness, conductor passage and behaviour during rainy conditions. Conductor vibration was reduced, and the sag and tension of triple-bundled conductors were easier to control. As a result, there were almost no stringing problems attributable to the pulleys, and rework caused by conductor surface damage was significantly reduced. At the end of the project, the Thai customer confirmed that this batch of SHSQN320X60(S) triple stringing pulleys helped them save considerable time on adjustment and rework, increased daily stringing output, and improved the final conductor quality. They are planning to continue using the same model in upcoming line refurbishment and new-build projects, and are also willing to recommend our triple stringing pulleys to other local contractors as a preferred choice for bundled conductor stringing in Thailand.

The equipment is being used for grounding and conductor stringing operations in high-voltage transmission projects. Finland’s grid construction imposes very high standards on safety and equipment reliability. Due to low temperatures, high humidity and long outdoor working periods, conventional steel ropes and pulley systems often suffer from slippage, unstable tension and poor grounding performance. The customer sought a solution that would ensure CE-compliant safety, stable pulling performance, and cold-weather durability. Our Pilot Steel Wire Rope is made of high-carbon galvanized strands with high tensile strength and excellent flexibility. The product is CE-Marked, guaranteeing conformity with EU safety regulations. Each 800 m reel (YL22-12XT25 cable reel) enables efficient lifting, handling and continuous stringing over long spans. The matching Grounding Roller Stringing Blocks SHSQN822D and SHD660D use reinforced aluminum alloy frames and sealed anti-freeze bearings, maintaining smooth rotation even at −20 °C. They reduce conductor friction and vibration during current discharge, ensuring consistent grounding safety. According to customer feedback: “Compared with our previous un-certified products, this combination performs significantly better in tension control, conductor protection and cold-weather reliability. Installation is simple, operation is stable and quiet, and overall stringing efficiency improved by nearly 30 percent." The Finnish contractor has since designated this configuration as the standard solution for future transmission-line expansion projects.
