Import 500mm2 Xlpe Copper Cable 16 Kv — Buy in Bulk from Supplier in China

This 500 mm² XLPE insulated copper conductor cable from Zhengzhou Zms Cable Co., Ltd. is rated for 16 kV applications, combining a large cross-sectional area with cross-linked polyethylene dielectric for medium-voltage power distribution. The substantial 500 mm² copper conductor provides low electrical resistance and high current-carrying capacity, suitable for primary feeder circuits and heavy industrial loads. XLPE insulation offers superior thermal stability compared to traditional PVC, withstanding higher continuous operating temperatures and reducing thermal ageing over decades of service. The 16 kV voltage class positions this cable for utility substation connections, industrial plant distribution, and renewable energy collection systems where medium-voltage transmission is required.

Cross-linked polyethylene achieves its enhanced properties through chemical or physical cross-linking of polymer chains, creating a thermoset material that does not melt or drip under short-circuit temperatures. The 500 mm² conductor size is typically constructed as compacted stranded copper, either circular or sector-shaped, to optimise cable diameter and bending radius while maintaining conductivity per IEC 60228 Class 2. Standard industry practice for 16 kV XLPE cables includes concentric neutral wires, a metallic screen, or both, depending on the application and earthing system, though the specific construction of this Zhengzhou Zms variant requires direct confirmation. Sheathing materials commonly include PVC or PE for mechanical and moisture protection, with armour options for direct burial or conduit installations.

Primary buyers of 500 mm² 16 kV XLPE cable include power utilities, wind and solar farm developers, heavy manufacturing facilities, and infrastructure contractors executing grid extension projects. The cable's large conductor size minimises resistive losses over long feeder runs, improving overall system efficiency. When sourcing from Zhengzhou Zms Cable Co., Ltd., buyers should confirm whether the cable conforms to IEC 60502-2, GB/T 12706.2, or another recognised standard, and request type test reports including partial discharge measurements and AC withstand voltage tests. The source description mentions ISO and CE certifications, though buyers must verify current certificate scope and validity directly with the supplier.

Zhengzhou Zms Cable Co., Ltd. is situated at Changzhuang Village, Fumin Road, Zhengzhou 450042, Henan Province, China, positioning it inland with provincial capital access with connection to Qingdao or Tianjin ports for seaborne export. The company holds a harbor trust tier and an imported supplier tier, the latter indicating platform-processed import credentials or documentation. The response rate is recorded at 0.00 percent with zero average response hours, suggesting no platform-mediated communication history. No factory size, year of establishment, annual revenue, employee count, or specific production capacity is disclosed in the available profile data.

The supplier's product focus, as represented by this listing, centres on medium-voltage power cables with copper conductors and XLPE insulation for industrial and infrastructure applications. The source description references ISO and CE certifications, though the scope, issuing bodies, and validity dates of these certificates are not detailed. Buyers should independently verify certification authenticity and whether Zhengzhou Zms operates as a manufacturer or trading company. The absence of platform response history means direct enquiry via the Henan address or alternative contact methods may be necessary for technical negotiations, sample requests, or factory audit arrangements.
