                Silane cross-linked polyethylene overhead insulation materials (specially used for export)
                 
                Characteristics and Purpose:
                Characteristics: designed for customer's special requirements, the dispersion of carbon black is good, and the heat shrinkage index of cable is stable and ultraviolet resistance . Excellent performance The direct contact between the insulation layer of cable produced by the user and the copper core still has good thermal oxidation stability.
                Purpose: used as insulation layer of 0.6 ~ 1kV LV overhead cable.
                Packaging, transportation and storage
                Packaging: aluminum-plastic composite damp-proof package: 25kg/ bag;
                Transportation Handle with care to avoid breaking the bag;
                Storage: the moisture absorption property of product is strong, the product shall be used immediately after opening the packaging, and the pre-drying is not necessary;
                If the product is not used completely, it is required to be sealed, and the  time interval for subsequent use should not be too long; otherwise, the extrusion appearance will be affected.
