Eight checks between the copper rod and the drum label, with results printed on every mill test certificate. Certificates stated with their actual scope — no borrowing a scope from a certificate we do not hold.
Copper rod and aluminium rod are checked for diameter, tensile strength and elongation before drawing. The conductivity of copper rod must meet 100% IACS minimum on a random sample per coil.
Breakage rate and wire diameter are monitored continuously. Annealed wire is verified for elongation and resistivity, which sets the conductor's flexibility class.
Strand count, lay length and lay direction are checked against IEC 60228. Class 5 and Class 6 conductors use finer wire and shorter lay length to reach the flexibility figure.
Wall thickness is measured online by laser micrometer. Eccentricity is held within 15%, which is the value most failures trace back to. Sample lengths are taken at the start, middle and end of every run.
Core identification is verified visually and by continuity. Steel tape gap and overlap ratio are checked on every armoured run; insufficient overlap is the usual cause of armour failure during pulling.
Overall diameter, minimum sheath thickness and surface finish are checked. Spark testing at the specified test voltage runs inline for every metre of insulated core.
Conductor resistance, insulation resistance, and high-voltage withstand per IEC 60502-1 or the applicable standard. Results are printed on the mill test certificate shipped with each drum.
Length measurement, drum condition, end sealing and label accuracy. Length is measured by calibrated counter and cross-checked against drum rotative registration.
Quality management system covering design, manufacture and export of power, control and special cable
Audited annually. Scope wording on the certificate matters when a consultant checks it against your tender requirements — ask us for the scope page before you submit.
Environmental management, including waste water treatment and copper recovery
Increasingly requested by European and Middle East utility tenders as a pass/fail gate rather than a scoring item.
Occupational health and safety management across both plants
Required by most EPC pre-qualification questionnaires before a site audit is scheduled.
Construction products regulation fire performance classification for building cable
Euroclass reaction-to-fire classes available up to Cca-s1,d1,a1 for halogen-free constructions, with declaration of performance and DoP labelling.
Certified solar photovoltaic cable to EN 50618 / IEC 62930
This is our only type-approved certification and we do not extend the claim beyond solar cable. Certificate number and valid date are provided in full on request.
Building wire manufactured to UL 83 and applicable appliance wiring material requirements
Available for North American and other UL-aligned markets. File-level confirmation is provided per order.
Compliance for Australian and New Zealand markets
Covering building wire and selected low-voltage power constructions to AS/NZS 5000.1.
Compulsory certification for cable sold inside China
Relevant when your project has a domestic Chinese scope alongside the export package.
Restriction of hazardous substances and SVHC declaration
Full substance declarations supplied with the order for European importers who need them on file.
For first orders we recommend witnessed testing. Inspectors from SGS, Bureau Veritas, Intertek and TÜV work from our plant regularly.
Reduced cross-section is the most common fraud in this industry because it is invisible once the cable is installed. Measured DC resistance versus the IEC 60228 maximum exposes it immediately. We publish the measured value, not the nominal one.
Include cross-section, core count, voltage grade, route length and installation method — those five determine price more than anything else on the page.
