Manufacturing Process for Composite Insulators
We could produce 200 pieces Tension insulator for electrified railway per day in one machine, and could use more machines if delivery time urgent and in big quantity.We have 9 injection machines could produce this item.
Inspection Before Shipment
Before dispatched, the goods will be performed routine test and sample test comply with related standards. In case damage during the transportation, each one’s sheds and housing will be checked thoroughly. Superficial defects of an area greater than 25 mm² (the total defective area not to exceed 0.2% of the total insulator surface) or of depth greater than 1mm.
Package
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.
Each container shall be marked with the number of insulators it contains, the catalog number, the manufacturer’s name, and any other customer requests.
Each packing (wooden cases or crates) attached specification and certification of products.
