Import Bs215 Standard 70mm2 Acsr Overhead Conductor — Buy in Bulk from Supplier in China

The BS215 Standard 70mm2 ACSR Overhead Conductor from Zhengzhou Zms Cable Co., Ltd. is a stranded aluminium conductor steel reinforced (ACSR) cable built for medium-voltage overhead power transmission networks. The 70mm2 nominal cross-sectional area provides a current-carrying capacity suited to rural distribution lines and secondary substation feeders where mechanical strength must resist wind and ice loading. Its construction follows the British Standard BS215, which specifies the mechanical and electrical properties of ACSR conductors for temperate and tropical climates. The aluminium strands carry current while the galvanised steel core bears tensile loads, a pairing that has dominated utility engineering since the 1920s.

ACSR of this class typically uses hard-drawn aluminium wire of 1350 grade with a minimum conductivity of 61% IACS, wrapped around a steel core of galvanised wire to ASTM A475 or EN 10244 class A coating. The steel-to-aluminium ratio in a 70mm2 BS215 conductor is usually around 6:1 by cross-section, giving a typical ultimate tensile strength of 12-15 kN and a weight of approximately 290-310 kg per kilometre. The outer aluminium layer is stranded in a concentric-lay pattern, with standard lay lengths of 10-14 times the conductor diameter to control reactance and prevent bird-caging under tension. Buyers should confirm the exact stranding configuration (aluminium/steel count) and whether the supplier provides sulphur-steel testing for corrosive environments.

Distribution utilities, rural electrification agencies and EPC contractors working on grid-extension projects are the primary purchasers of this conductor grade. It is commonly deployed on wooden or concrete poles with standard pin or suspension insulators at spans of 80-150 metres depending on terrain and loading zone. The conductor is supplied on non-returnable wooden drums or steel reels, with drum lengths typically 2,000-4,000 metres to minimise field joints. Trade terms from Henan-based manufacturers often quote FOB Tianjin or Qingdao, though the buyer must confirm Incoterms, packing charges and drum deposits directly with Zhengzhou Zms Cable Co., Ltd. given its zero percent response rate on the platform.

Zhengzhou Zms Cable Co., Ltd. is located at Changzhuang Village, Fumin Road, Zhengzhou 450042, in Henan Province, a central Chinese region with established wire and cable manufacturing clusters. The supplier carries a 'harbor' trust tier and an 'imported' supplier tier, indicating it has passed baseline platform verification for cross-border trade. Its response rate is recorded at zero percent with no average response time logged, which prospective buyers should note when planning procurement timelines and communications.

The supplier profile does not disclose factory size, year of establishment, revenue, workforce numbers, specific certifications held, or named domestic and international clients. No MOQ, price band, lead time, or accepted payment terms are listed in the available data. Buyers should therefore request a company profile, factory audit report, and reference projects before committing to an order, and should plan for extended initial contact given the response statistics.
