Product Description

At present, composite polymer post insulators are widely used in power gridtransmission lines, accounting for about 50% of the line silicone rubber insulator consumption. Among them, the proportion of linear towers is higher. Almost all linear towers in heavily polluted areas use composite insulators. Composite polymeric insulators have solved the pollution flashover problem that has plagued the power grid for many years with their excellent anti-flashover performance.

Packaging & Shipping

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.
