The company holds the most advanced Automatic Silicone Injection Molding Machines and Voice-operated Displacement Crimping Machines which means the world's most advanced process technology level.
We have implemented advanced management and set up a strict quality management system according 1- 1509001 : 200S. All the products' quality requirements comply with IEC61109, IEC62231, G3/T19519-2004,GE/T 22079-200s, DU/T 1048-2007.DL/T810-2002 and TE/T3199.2-200g Standards, etc.
1. All composite insulators are packed in weatherproof containers in order to protect the products during land, air, and sea transportation. Several different grades of packaging can be offered depending on the mode of transport and the expected storage conditions. The packaging options that we offer are
1) standard grade/prefabricated packing
2) economical grade/cardboard carton
3) best grade/closed wooden crate
Since the user best knows their crate requirements, they should select the option that is most suited to their needs and include that information in the purchasing specification. Special packaging arrangements can be accommodated upon request.
2. Each container is marked with the number of insulators it contains, the catalog number, the manufacturer's name, and any other customer requests.
3. Each packing (wooden Cases or Paper ubes) attached specification and certification of products.
