Description du produit
Beijing Huayuan Gaoke Cable Co., Ltd a été créé en 1998, situé dans le district de Daxing à Beijing en Chine. L'usine couvre une superficie de plus de 20.000 mètres carrés et a dix-huit équipements de production avancés nationaux et étrangers de câbles d'alimentation jusqu'à 110kv câbles isolés par XLPE. Société a introduit avec succès des lignes de production de câbles en alliage d'aluminium, ligne de production de câbles résistant au feu isolées minérales et ligne de production de câbles en caoutchouc de silicone en 2012. La société vise à rechercher qualité parfaite, innovation technologique, efficacité énergétique et protection de l'environnement. Huayuan est devenu une étoile montante dans les entreprises high-tech chinoises du câble. Les entreprises ont adopté la certification ISO9001: 2008 système de gestion de la qualité, certification GB / T28001-2011 de santé et de sécurité au travail, ISO14001: 2004 certification de gestion environnementale, certification CCC, le permis de production industrielle nationale, fournisseurs qualifiés de bureau d'alimentation électrique à Beijing sur, le câble isolant de feu resitent le BSI CERTIFICATE comme BS 6387: 2013, tous les produits rencontrent les normes nationales de fil et de câble. nos câbles avaient été exportés vers l'Asie du sud-est, l'Europe, Amérique du Nord, Amérique du Sud pour beaucoup de projets principaux.
