Product beschrijving
Beijing Huayuan Gaoke Cable Co., Ltd. werd opgericht in 1998 en is gevestigd in het district Afslag in Beijing, China. De fabriek heeft een oppervlakte van meer dan 20.000 vierkante meter en heeft achttien binnen- en buitenlandse geavanceerde productieapparatuur voor stroomkabels tot 110kv XLPE geïsoleerde kabels. Het bedrijf introduceerde met succes aluminiumlegeringskabelproductielijnen, mineraal geïsoleerde brandwerende kabelproductielijn en productielijn van siliconenrubberkabels in 2012. Het bedrijf streeft naar perfecte kwaliteit, technologische innovatie, energie-efficiëntie en milieubescherming. Huayuan is een opkomende ster geworden in Chinese hightechbedrijven van de kabel. De ondernemingen hebben de ISO9001: 2008-certificering van het kwaliteitsborgingssysteem, GB / T28001-2011 certificering voor gezondheid en veiligheid op het werk, ISO14001: 2004 certificering voor milieubeheer, CCC-certificering, de nationale vergunning voor industriële productie, gekwalificeerde leveranciers van elektriciteitsleveranciers in Beijing en zo, op, de mineraal geïsoleerde brandveilige kabel doorgegeven BSI CERTIFICAAT als BS 6387: 2013, alle producten voldoen aan de nationale draad- en kabelstandaarden. Onze kabels zijn geëxporteerd naar Zuidoost-Azië, Europa, Noord-Amerika en Zuid-Amerika voor veel belangrijke projecten.
