1. Project Core Challenges
Xiangtang substation is a key power hub connecting multiple 110kV &35kV power nodes in Lanzhou Honggu District. The expansion project needed synchronous laying for multi-loop cross-section cables inside compact indoor cable duct rooms. Key construction pain points: Limited indoor working space forbids bulky heavy machines; synchronous laying for multiple parallel cables required uniform traction speed to avoid cable twisting; frequent short-distance shifting of laying positions led to low efficiency of traditional fixed conveyors.
2. APEX Customized Product & Service Solution
APEX’s core matching product is Tank900 intelligent remote-controlled cable conveyor, equipped with flexible crawler chassis for easy indoor relocation, intelligent grouping frequency conversion to realize synchronous speed for multi-machine linkage; supporting mini SA-QY-50 hydraulic tensioner for vertical high-floor cable pulling. Pre-sales technical team finished on-site duct measurement and customized grouping parameter setting within 3 working days; on-site after-sales engineers stayed for 15 days to guide equipment debugging and operator training. All machines pass ISO9001 & CE certification for stable indoor continuous operation.
3. Final Project Outcomes
Tank900’s movable design cut equipment relocation time per working point by 70%; multi-unit intelligent linkage eliminated cable twisting risk completely; multi-circuit synchronous cabling efficiency improved by 40%, the whole expansion cable construction completed ahead of plan, winning positive evaluation from State Grid Lanzhou Power Supply Company’s engineering department.
