Silane cross-linked polyethylene insulation material
Feature and Usage
l One-step method: the equipment investment is less, the operation is simple, the cost is low, and the quality guarantee period is up to 1 year. Temperature control when the product is used. Strict requirements and high operating process requirements.
l Two-step method: the equipment investment is large, the cost is high, the quality guarantee period is up to half a year. The temperature is easy to be controlled when the product is used, and setting-out speed is fast and the quality stability is good (mainly shown on the appearance quality and thermal shrinkage index of cable).
l Purpose: used as the insulation layer of 0.6 ~ 10KV medium and low-voltage power cable and overhead cable
Packaging, transportation and storage
Packaging: aluminum-plastic composite dampproof package: 25kg/ bag (in two-step method, catalytic masterbatch B with small bag packing is contained inside the material );
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.
