                Peroxide cross-linked polyethylene insulation materials
                Feature and Usage
                l CharacterIstics: the special electric cable materials are adopted, the raw materials are pure, the temperature in the production process is not more than 110, and the processing performance is stable. The product is provided with good thermal oxidation stability;
                l Application: used as the insulation layer of medium-voltage power cable and overhead cable in 10 ~ 35KV level.
                 
                Packaging, transportation and storage
                Packaging: moisture prevantion for PE inner film bag , carton packaging,  wooden pallet cushioned underneath,  500 kg/ box for packaging;
                 
                Transportation :Handle with care to avoid breaking the bag;

                Storage: immediately use after opening the package, it is unnecessary to carry out the pre-drying; If the product is not used completely, it is required to be sealed and used for subsequent use.
