Import Adss Suspension Clamp — Buy in wholesale FOB from Supplier in China

Shijiazhuang Huaneng Electric Power Fitting Co., Ltd. produces this ADSS preformed suspension clamp for mounting all-dielectric self-supporting fiber optic cables on utility poles and transmission towers. The clamp body is cast from Aluminum Alloy 6063-T5, a grade selected for its balance of extrudability, corrosion resistance, and moderate strength in overhead hardware applications. A UV-resistant neoprene cushion sleeve lines the cable contact surface to prevent abrasion and compressive damage to the ADSS sheath. The rear hinge mechanism permits tool-free opening and closing around the cable, reducing installation time and eliminating the need for loose fasteners during fitting.

The clamp assembly includes stainless steel bolts and locking washers for secure closure after cable placement. Preformed suspension clamps distribute mechanical load along a length of cable rather than concentrating stress at a single point, reducing the risk of sheath compression and fiber microbending. The source describes variants for short spans with O-ring fittings, mid-to-long spans with aluminum-clad armour, and single versus double clamp configurations depending on tower spacing. The neoprene insert material must withstand prolonged UV exposure and temperature cycling without hardening or cracking, as degradation would expose the cable to direct metal contact and potential sheath failure.

Intended buyers are telecom network contractors, utility companies, and broadband infrastructure developers deploying FTTH and OSP fiber networks. The clamp is specified for high-voltage environments above 220 kV where corona discharge and electrical field effects must be managed through proper hardware design. Available sizing covers multiple ADSS cable diameters to match different fibre counts and sheath constructions. Buyers should confirm the exact cable outer diameter range, rated breaking load, and compatibility with their pole hardware interface dimensions before ordering.

Shijiazhuang Huaneng Electric Power Fitting Co., Ltd. is located at No.189 Hengshan Street, Shijiazhuang High-Tech Zone, Hebei Province, China. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and average response hours at zero, indicating limited active engagement data is currently available. The company operates from a high-tech zone address, suggesting access to regional metal casting and electrical hardware manufacturing infrastructure. Buyers should conduct direct due diligence to confirm current production status and export experience.

The supplier's product focus covers preformed suspension and tension clamps for ADSS and overhead line conductors. No factory audit reports, ISO certification details, annual turnover, employee counts, or named client projects are present in the source data. The material specification of Aluminum Alloy 6063-T5 and UV-resistant neoprene is explicitly stated, which buyers can verify against incoming inspection and material test certificates. Prospective purchasers are advised to request sample clamps for dimensional and load testing, and to confirm whether the supplier maintains in-house die-casting or sources castings externally before machining and assembly.
