Wind and solar farms require extensive underground cable networks. The key equipment includes high-capacity cable pulling winches (hydraulic or electric), heavy-duty cable drum stands to handle large collector cables, and a complete set of trench rollers to minimize pulling friction and protect the cable jacket. We have extensive experience supplying equipment for these large-scale renewable projects.

Straight-line rollers are used for open trenches. Corner rollers (3-roller type) are essential for navigating bends and manholes without exceeding the cable's minimum bend radius. Manhole rollers and bell mouth guides are used to protect cable at the entry and exit of ducts. Using the wrong roller can damage the cable sheath and lead to project failure.

The main methods are: 1) Open-Cut Trenching: The most common method. We supply cable rollers (straight, corner, and manhole), cable drum jacks, and cable pulling winches. 2) Trenchless (HDD): Used for crossing roads or rivers. We provide conduit duct rodders and heavy-duty pulling swivels. 3) Micro-Trenching: For fiber optics, requiring specialized rollers. We are the one-stop shop for all associated laying tools.

A full stringing operation requires more than just a puller and tensioner. We provide the complete package, including conductor stringing blocks, pilot wire rope, swivels (to prevent twisting), conductor grips (come-along clamps), running boards (head boards), and reel stands (drum elevators).

Yes. Stringing ACCC conductors requires specialized equipment. The key is precise tension control and non-damaging handling. Our hydraulic puller-tensioners offer smooth, calibrated tension, and our polymer-lined stringing blocks are specifically designed to prevent damage to the conductor's sensitive composite core.

Stringing blocks are pulleys that guide the conductor along the transmission towers during installation. The groove lining is critical. We offer nylon or polyurethane-lined grooves, which are essential to protect modern conductors like ACSR and ACCC from damage, unlike traditional aluminum grooves.

Selection depends on four key factors: 1) Conductor Type & Size: This determines the required pulling force (kN) and tension. 2) Line Length: Longer pulls may require larger bull-wheel diameters and higher rope capacity. 3) Terrain: Difficult terrain may necessitate equipment with advanced controls or remote operation. 4) Project Scale: Whether it's a single line or a large-scale OHTL project. Our technical team can provide a precise recommendation based on your project specs.

A Hydraulic Puller is used to pull the pilot rope or conductor. A Hydraulic Tensioner provides controlled back-tension to keep the conductor off the ground and prevent damage. A Hydraulic Puller-Tensioner is a versatile machine that can perform both pulling and tensioning, making it ideal for various stringing operations, including reconductoring. As a one-stop supplier, we offer a full range of all three.

Check local permits for excavation, assess impact on utilities and ecosystems, plan for reinstatement of surface, and prefer trenchless methods where permits or urban disruption limits open trenching.

Compare SWL, duty cycle, warranty, after-sales support, spare parts lead times, available test reports, and field references. Ask for FAT videos and third-party inspections when needed.

Apply 'ground first, connect second' rule when using grounding blocks; ensure reliable ground paths, test continuity before pulling, and remove grounding devices only after de-energized confirmations.

Yes—we offer on-site commissioning, operator training, and technical support packages. Training includes safe operation, daily maintenance, and troubleshooting.

Include equipment rental/purchase, transport, labor, training/supervision, permitting, site access works, consumables (wire rope, blocks), and contingency for weather delays.

Common causes include contaminated hydraulic fluid, worn seals/hoses, overloaded pulls beyond SWL, improper rigging, and lack of periodic maintenance.

Asia-Pacific (including Southeast Asia), North America, and parts of Europe show heavy investment for fiber backbone projects and grid modernization—APAC growth is especially strong for wire & cable demand.

Provide conductor specs, maximum span length, required SWL, operating environment, power supply availability, and any mounting or transport constraints. Ask for drawings, factory acceptance tests (FAT), and on-site commissioning support.

How-to tutorials (equipment setup, maintenance), time-lapse of stringing jobs, safety procedures, equipment comparison (30-ton puller vs 20-ton), and customer case studies with on-site footage.

Survey access roads, set up stable anchor/foundation points, plan for helicopter lifts if needed, use elevated blocks or tensioners, and create detailed safety and rescue plans.

Datasheets should include SWL, max pull speed, hydraulic pressure & flow, weight & dimensions, drum/winch capacity, wire rope specs, duty cycle, and required power pack ratings.
