PVC honeycomb tube selects the high-quality PVC resin as the main raw materials, with a selected combination formula by mixing extrusion molding of a new type of fiber optic cable protection tube. It is applicable to the guide isolation and protection of communication optical cable. Honeycomb tube has strong compressive ability, stressed uniformity, compact structure. Its various performance indexes meet the industry standard requirements, and has obvious advantages of improving the utilization ratio of tube hole, reduce engineering cost, improve work efficiency and easy installation. It can be widely used in optical fiber communication, cable TV, multimedia transmission and other projects.
