►Advantages
1, There is a professional design engineer team, before manufacturing, all of the product drawing will be approved by CSBTS (State Bureau of Quality Technical Supervision), and then the cable could be produced only if qualified.
2, To ensure the raw materials quality, all the copper are special-used for cable with the Inspection Certificates. The raw material is inspected when entering factory, and only the qualified material could be put in storage and used for production.
3, To ensure the product quality, there is a professional high level quality laboratory, most of the key technology date will be checked by high precision instrument
4, To ensure no problems before delivery, all the raw materials and cables are supervised and inspected again by the experts of inspection institution for inspection institution for cable. we could offer the international quality certification of ISO9001 and CE, and the inspection report of SGS, BV, etc, Quality Certificates.
