1. Project Core Challenges
The 110kV Guoyang smart substation is built to optimize local power grid framework and supply power for southern towns of Guoyang. During early construction, the contractor faced three tough troubles: Traditional manual cable pulling needed over 30 field workers for medium-sized power cable routing; frequent artificial dragging caused outer sheath scratch of 3–24cm diameter main cables; tight construction schedule required finishing all cable laying within 28 days while manual mode failed to hit the target. Besides, narrow cable trench space limited large heavy-duty construction machines’ entry.
2. APEX Customized Product & Service Solution
APEX team provided one-stop solution with Enhanced 900 dual-track cable conveyor and Lijian No.6 shaft-drive electric winch, matching on-site parameters: Enhanced900 supports 2–24cm cable diameter, 8000N single machine pulling force, remote IoT wireless control and multi-unit linkage to arrange multiple conveyors along cable trenches; Lijian No.6 electric winch features stable 50kN rated traction and automatic brake for vertical shaft cable pulling. Our pre-sales engineers finished on-site survey & customized layout plan within 72 hours; after-sales team dispatched technical instructors to site for free machine operation training before construction starts.
3. Final Project Outcomes
Only 8 construction operators ran all equipment instead of 30+ laborers, cutting total labor cost by 68%; zero cable scratch damage during full laying progress; all cable installation work finished 5 days ahead of scheduled deadline, helping the substation pass grid acceptance smoothly on time. The client purchased extra spare parts under APEX’s global spare inventory support for future maintenance.
