从China供应商批量进口4 Cores Telephone Cable

This four-core telephone cable from Zhejiang Jiahui Wire & Cable Co., Ltd. in Ningbo, Zhejiang Province, is built around bare copper conductors arranged in a stranded configuration for voice and low-speed data transmission. The PE-insulated cores suit indoor and protected outdoor runs in residential blocks, small offices, and legacy PBX systems where cost-effective copper infrastructure remains viable. The four-pair design supports two simultaneous lines or basic line-sharing configurations common in older buildings and rural upgrades.

The stranded copper construction offers better flex life than solid-core alternatives, which matters during pull-through conduit and in environments with modest vibration. PE (polyethylene) insulation provides stable dielectric properties across normal temperature ranges and resists moisture ingress better than basic PVC in unconditioned spaces. Industry-standard telephone cables of this type typically carry conductor diameters between 0.40mm and 0.50mm (26 to 24 AWG equivalent), though the exact gauge should be confirmed with the supplier. Sheathing options for similar cables usually include PVC or LSZH (low smoke zero halogen) jackets, with the latter required for public buildings and transit infrastructure in many jurisdictions.

Buyers sourcing this cable from Ningbo should verify whether the supplier stocks IEC 60227 or GB/T 5023 harmonised constructions, as Chinese domestic and export variants differ in colour code and sheath thickness. The cable suits fixed installation in dry or damp environments, ducted or trayed, but is not rated for direct burial without additional mechanical protection. Typical applications include telecom refurbishment, hospitality retrofit, alarm system interconnection, and copper backup lines in hybrid fibre-copper networks.

Zhejiang Jiahui Wire & Cable Co., Ltd. is located on Jinhui West Road in Yinzhou District, Ningbo, Zhejiang Province, China (postcode 315100), placing it within one of China's densest cable manufacturing corridors with access to Ningbo-Zhoushan Port for export shipment. The supplier holds a 'harbor' trust tier on the platform, which indicates a baseline verification level, though buyers should conduct independent diligence. The response rate shows 0.00 percent with zero average response hours, meaning direct enquiry is essential and buyers should not assume prompt reply.

The listing positions the company as a manufacturer of telecommunication cables with flexible order quantities, but no verified factory audit, export licence, or ISO certificate numbers are displayed. The source description mentions ISO and CE certifications without reference numbers or scope, so buyers should request current certificates and test reports directly. No employee count, annual turnover, or specific history is stated, and none should be assumed. The product range centres on copper communication cables, with this four-core telephone cable representing a standard stock or production-line item rather than a specialised custom build.
