Cable Materials — Industries & Applications
Cable materials — conductor, insulation, shielding and sheathing — are an additional supply category for Zhongbo. They are sourced from confirmed manufacturers, not produced in-house: for every item the manufacturer identity, grade, applicable standard and country of origin are confirmed before the order is accepted, and the mill or test documentation the project requires is provided. Zhongbo is the supply and documentation contact for these materials, not their manufacturer.
This page sets out the industries and cable types that Zhongbo-supplied cable materials serve, and which layer of the cable each material group applies to. For the full catalogue by material group see the cable materials product hub; to request a quote use the cable materials RFQ checklist.
Across every industry below the model is the same: the buyer specifies the application, material and standard; Zhongbo identifies a confirmed source, confirms grade and origin, and supplies with the documentation the project acceptance requires.
Challenges in cable materials
Cable manufacturers and project buyers sourcing bought-in cable materials face recurring supply-side challenges:
- Material supplied without confirmed manufacturer identity, grade or standard conformance — a certification gap that can hold up cable approval or project acceptance.
- The same compound graded differently under different standards (IEC, BS, ASTM, GB/T), so a material stated without its standard cannot be firmly quoted.
- Voltage class and cable layer (conductor, insulation, shielding, sheathing) not stated, so the wrong grade is sourced.
- Certificate and inspection requirements raised after the order, changing the source and the lead time.
- Multiple materials for one cable design bought from separate suppliers, each with different documentation formats and lead times.
Power cable manufacturing
Power cable makers source conductor, insulation, shielding and sheathing materials for low-voltage, medium-voltage and high-voltage cable designs. Zhongbo supplies these against the cable standard and voltage class, with grade and origin confirmed per order and the documentation the design approval requires.
- Conductor — aluminium and copper in rod, strip or shaped form
- Insulation — XLPE and PVC compounds to voltage class
- Shielding — aluminium and copper tapes and braids
- Sheathing — HDPE and PVC compounds
Telecom & data cable
Telecom and data cable production draws on conductor, shielding and sheathing materials where consistency and documented grade matter for signal performance. Materials are sourced to the applicable standard with certificates confirmed per order.
- Conductor — copper (bare and tinned) in fine sizes
- Shielding — aluminium/copper foil and braid
- Sheathing — PVC and specialty compounds
Instrumentation & control cable
Instrumentation and control cables require carefully specified shielding and sheathing to protect low-level signals. Zhongbo sources these materials against the buyer's standard, with the certificate and any inspection agreed before the order is placed.
- Shielding — foil and braid to specification
- Sheathing — flame-retardant and standard compounds
- Conductor — copper to required grade
Building wire & installation cable
Building and installation wire uses conductor and insulation materials to national and international standards. Materials are supplied against the stated standard and grade, with documentation provided for compliance.
- Conductor — copper and aluminium
- Insulation — PVC and low-smoke compounds
Specialty & industrial cable
Specialty and industrial cables — flexible, fire-resistant, marine and other application-specific designs — use materials selected to the project specification. Zhongbo sources to the stated requirement and confirms grade, origin and documentation per order.
- Materials sourced to the project or application specification
- Grade, standard and origin confirmed before order acceptance
- Documentation and inspection agreed at enquiry stage

Standards & compliance
Supplied cable materials are sourced against the standard the buyer specifies — IEC, BS, ASTM, GB/T or a project specification — with the applicable grade, standard and origin confirmed per order. Zhongbo does not manufacture these materials; it sources them from identified manufacturers and provides the mill or test documentation (test report, certificate of compliance, RoHS/REACH where required) the project requires. Documentation and any third-party or witnessed inspection are agreed at the enquiry stage.
Why cable materials buyers choose Zhongbo
Cable makers, EPC and project procurement teams and distributors source cable materials through Zhongbo because the supply chain and its documentation are handled to a single account. What sets the service apart:
- Manufacturer identity, grade, applicable standard and origin confirmed before order acceptance for every supplied item.
- One supply and documentation contact for conductor, insulation, shielding and sheathing across a cable design.
- Sourcing against the buyer's standard and approved-manufacturer list where a project mandates one.
- Mill or test documentation — test report, certificate of compliance, RoHS/REACH — provided as the project requires.
- Clear manufacture-vs-supply account: Zhongbo represents itself as the supply contact, never as the manufacturer of these materials.

Frequently Asked Questions
Does Zhongbo manufacture these cable materials?
No. Cable materials are an additional supply category, sourced from confirmed manufacturers. Zhongbo confirms the manufacturer, grade, standard and origin before order acceptance and provides the documentation you require, acting as the supply and documentation contact rather than the manufacturer.
Which industries do you supply cable materials for?
Power cable manufacturing, telecom and data cable, instrumentation and control cable, building wire and specialty or industrial cable. The material group — conductor, insulation, shielding or sheathing — is sourced to your application and standard.
Can you meet a specific standard or approved-manufacturer list?
Yes. Send the standard and any approved-manufacturer list the project mandates; the applicable grade, standard, origin and documentation are confirmed against your specification before the order is accepted.
What documentation is provided?
For each supplied material Zhongbo provides the mill or test documentation the project requires — test report, certificate of compliance, or RoHS/REACH where applicable — with any third-party or witnessed inspection agreed at the enquiry stage.
How do I get a quote?
Use the Cable Materials RFQ Checklist to send the application and cable type, material and grade, voltage class or standard, quantity, certificates and destination port. The more precisely these are stated, the faster and firmer the quote.
