Sound Testing Equipment
The company is equipped with 1000kV Power Frequency Testing Transformer, 1800kV Impulse Voltage Generator set and 2000kN Automatic Tensile Test Machine, as well as well-equipped Physical Laboratory and Electrical Laboratory.
Advanced Manufacturing Equipments
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 been participating in various exhibitions at home and abroad from 2010 to 2020. At the exhibition, relevant people from the industry and us saw our products directly and closely.
1. All polymer 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, and
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 electrical 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.
