Import Adss With The Dn Short-Span Tension Clamp — Buy in wholesale FOB from Supplier in China

The DN Short-span Tension Clamp from Shijiazhuang Huaneng Electric Power Fitting Co., Ltd. secures All-Dielectric Self-Supporting fibre optic cables to poles and towers in overhead installations where span length remains below 100 metres. Its construction pairs a galvanized steel structural body with a UV-resistant polymer insert, creating a gripping interface that preserves cable dielectric properties while resisting solar degradation across extended outdoor exposure. The assembly includes twisted preformed wire, thimble, PH-type shackle, and U-type shackle, transferring tensile load from cable to support structure without exceeding the lateral pressure limits specified by cable manufacturers.

The polymer insert serves a dual function: it cushions the cable against point-loading from the metallic components, and its UV-stabilised formulation prevents embrittlement under continuous sunlight in tropical or high-altitude deployments. Galvanized steel provides the primary load path with sacrificial corrosion protection, with typical hot-dip coating processes delivering 80 to 120 micrometres of zinc layer for atmospheric exposure categories up to C3 under ISO 9223. Buyers should note that the exact polymer compound, Shore hardness, and temperature rating are not specified in the source, so these properties require direct supplier confirmation for projects in extreme climates.

Infrastructure contractors rolling out FTTH networks, rural broadband programmes, and utility pole-sharing schemes represent the core demand for this hardware. The clamp suits contractors who need non-conductive cable support on shared electrical infrastructure where galvanic separation is essential. Importers should cross-reference the grip strength rating, expressed as a percentage of cable RTS, against their specific cable datasheet before final specification. The supplier's location in Shijiazhuang High-Tech Zone positions it within Hebei's metals processing corridor, though proximity to raw material suppliers does not independently confirm manufacturing quality or export readiness.

Shijiazhuang Huaneng Electric Power Fitting Co., Ltd. is located at No.189 Hengshan Street within the Shijiazhuang High-Tech Zone, Hebei Province, China. The supplier holds a harbour trust designation, indicating basic platform registration without advanced verification. The response metrics show zero recorded activity, meaning prospective buyers cannot rely on historical responsiveness data and should test communication channels with a specific technical enquiry before committing to purchase timelines. The industrial address situates the company in a zone with established engineering activity, though this does not confirm on-site manufacturing versus trading operations.

The supplier's profile focuses on electric power fittings with particular emphasis on ADSS cable hardware. No ISO 9001, ISO 14001, or IEC product certification is indicated in the available data, and no export registration, annual turnover, or employee count is disclosed. Buyers must conduct independent due diligence, potentially including a factory visit or video inspection, to confirm production capability for the DN Short-span Tension Clamp and to verify that the galvanized steel and polymer insert are processed under controlled conditions. The absence of verified client references or project portfolios in the source means that track record assessment falls entirely to the importer's own qualification process.
