Winding fiber reinforced plastic cable sleeve of Hangzhou Xinlu Industries Co. Ltd is made by using VGZFW-2-250 computer-controlled winding machine, with DC-191 unsaturated flame-retardant polyester resin and glass fiber of direct woven roving as reinforcing materials.
This product can be a protective pipe to lay cables of urban power grid, and a protective pipe to lay electric cables at traffic artery. It matches with specific pipe pillows and intermediate connectors to form a cable conduit system with multiple rows of multiple pipes. With spigot and socket type structure, its connection is easy and reliable, its installation and construction is convenient. It properly solves big problems—for example, urban traffic is affected due to the road is dug and exposed for a long time. If the road is dug and cables are laid at night, the road can be backfilled and vehicles can pass as usual at daytime. In recent years, the glass reinforced plastic pipe, as a cable protective conduit with good quality and cheap price, has been universally promoted to be used as protective pipes in the United States, Japan, and Western Europe, etc. and has been widely used in urban grid transformation and new construction projects in the domestic large cities such as Beijing, Shanghai, and Wuhu.
The pipe is light in weight but high in strength, whose height is 1/4 that of a steel pipe, and about 1/8 that of a concrete pipe, and can be conveniently handled by one person.
With a smooth inner wall and small friction coefficient, this pipe doesn’t damage cables; and cables can pass through the pipe easily.
Non-magnetic and non electro-corrosion.
It is insulated, resistant to chemical corrosions; it doesn’t rust.
It is heat resistant, flame-retardant, with large carrying capacity, and can be used in an environment with temperature of 130℃, thus its performance is superior to cable protective pipes made of other materials.
Excellent cold resistance.
With good resistance to water, it can be used in a humid environment or water for a long time.
This pipe boasts of simple installation and construction at a low cost; since this pipe adopts spigot and socket type or muff-coupling type connection, it is convenient to install and connect. The connecting place is equipped with rubber seal ring, thus it is adapted to expansion caused by heat and contraction caused by cold.
With a low overall investment and quick outcome, this pipe brings great social and economic benefits.
With a long service life, it can be in use for fifty years without maintenance.
