Import Adss & Opgw Preformed Strain Clamp — Buy in wholesale FOB from Supplier in China

The ADSS and OPGW preformed strain clamp from Hebei Glame is a dead-end grip assembly engineered for overhead fiber optic cable installations in transmission and distribution networks. Each unit comprises inner armor rods, outer armor rods, a thimble, U-shaped hanging loop, extension rods, bolts and nuts for complete pole or tower mounting. The clamp is rated for grip forces of 30 kN up to 120 kN depending on model, with grip power not less than 95 percent of the optical cable's rated pulling resistance. Inner armor rod lengths range from 1900 mm to 2600 mm, while outer armor rod lengths span 1500 mm to 2000 mm across the ONZ series. Estimated unit weight runs from 2.9 kg to 5.0 kg, and all standard variants are finished in yellow for high-visibility identification.

The armor rods are fabricated from aluminum-clad steel and galvanized steel, materials selected for corrosion resistance and mechanical strength in outdoor aerial environments. The preformed helical design distributes tensile load evenly along the cable sheath, eliminating stress concentration points that could degrade optical fibers over time. This construction suits both all-dielectric self-supporting (ADSS) cables and optical ground wire (OPGW) configurations. Standard industry practice for such hardware follows IEC 61215 test criteria for mechanical load and environmental durability, though buyers should confirm specific compliance with the supplier. The thimble and U-loop geometry allows attachment to standard pole fittings without custom adapters.

These clamps deploy at terminal poles, corner poles and dead-end towers where cable tension must be fully transferred to the support structure. Typical buyers include telecom infrastructure contractors, utility network operators and system integrators rolling out fiber-to-the-tower or power-line communication projects. The HS classification for these assemblies is 8544.70, covering optical fiber cable fittings. Buyers should verify rated grip force against their cable manufacturer's tensile specification, and confirm outer diameter compatibility since model codes reference the optical cable OD in millimetres. No MOQ, pricing or lead time is stated in the listing; confirm these directly with Hebei Glame before placing an order.

Hebei Glame Import and Export Trade Co.,Ltd. is based in Shijiazhuang, Hebei Province, China, with its registered address at Room 11-2-201, Haideyuan No. 5, Yuxiang Street in the Yuhua District. The company holds a harbor trust tier on the platform, indicating a baseline verification level. Its response rate is recorded at 0.00 percent with an average response time of zero hours, which suggests the supplier has not yet established a track record of inbound enquiry response through this channel. Buyers should treat this as an unproven communication profile and initiate direct contact early in the sourcing process to gauge responsiveness.

The listing presents Hebei Glame as a trading company offering ADSS and OPGW preformed strain clamps for export, with product specifications spanning multiple mechanical ratings and cable diameters. No factory ownership, production capacity, year of establishment, employee count, revenue figure, client list or certification details (ISO, IEC, ASTM) are provided in the source data. The supplier's role appears to be trade-oriented rather than manufacturing-focused, though this is not explicitly confirmed. Buyers should request company registration documents, quality management system certificates and factory audit reports before committing to volume orders.
