how much you know the PVC communication hole tubeProduct Brief
The PVC communication hole tube uses PVC resin as the main material, and at the same time, an appropriate amount of stabilizer, lubricant, flame retardant, processing modifier and impact modifier is added and kneaded and extruded.
The seven-hole tube adopts a seven-hole honeycomb design and has an excellent overall compression structure. Its performance is due to plum blossom tube and bellows. No need for jacket protection, easy construction.
The product uses hard polyethylene resin as the raw material, which has the characteristics of acid resistance, aging resistance, flame retardancy and insulation. The service temperature is -20 ℃ to -40 ℃, and the life span is more than 30 years.
Due to the flexibility of the polyethylene material, the pipe has a certain degree of winding and can easily bypass obstacles.
The technical requirements of this product comply with the YD / T841-1996 industry standards of the Ministry of Posts and Telecommunications from 5.1, 5.2A, 5.3, 5.4.1, 5.4.2 and other standards
This product eliminates the need for jacket protection. Compared with bellows and sub-tubes, the cost per kilometer is greatly reduced.
It is widely used in basic projects such as optical fiber communication, cable TV, multimedia transmission, etc. It is a new type of practical photoelectric communication pipeline supporting product.
