Innovative Concept

With global climate change continues, environmental consciousness constantly enhanced among citizen; with rapid development of economy and modernization construction of our country, the national strategy turns to favor of Low-carbon and cyclic economy, which will push the traditional energy dissipation product to be improved and replace.

Therefore, after done sufficient research, we developed Macromolecule alloy cable tray and put into production. The manufacture process is first mix PVC, ABS, PS etc. unsaturated polyester resin and variety of polymer and high molecular resin with flame retardant chemical additives, then plasticizing the material, finally extrusion molding or injection molding, shaping and cutting. Its physical and mechanical features are better than metal cable tray. It will be the priority choice to replace metal cable tray in 21th century.

For its special design, macromolecule alloy cable tray is decorative and flexible. The installation is much less complicated than steel cable tray installation and need less fittings which will greatly improve efficiency and reduce cost.

Macromolecule ally cable tray has slot type, bore type and ladder type. It is combined by two part: baseboard and cover. The U groove of the bottom plate is a part of the cable. The double hollow structure is extruded continuously by the extruder. It not only has super strong mechanical structure, but also greatly reduces the weight of the product. Cover can be monolayer or double-layer. There is snap joint on baseboard and cover to connect each other. This design is easy to close and open, convenient for installation and maintenance, repair and technical reforming.

Petrochemical engineering is usually carried out in outdoor and extremely hostile environment perennially. The climate changing requires products to be high temperature resistance, low temperature resistant, aging resistance under strong UV light, anti-static and strong durability. Macromolecule ally cable tray has as UV-resistant, antioxidant and anti-static additives mixed in the material to enhance durability and safety.

● Civil building
Civil buildings can be divided into two categories: residential buildings and public buildings according to the function of use. The civil buildings in the People's Republic of China people's Air Defense Act refer to houses, hotels, guest houses, shops, teaching buildings and offices, scientific research and medical rooms. The "civil architecture" is different from "military buildings" and productive industrial buildings.

● Power industry
In 2015 the national Power Grid Corp operating area of society as a whole amount of 43721 kwh, the country is expected to power installed capacity of 1 billion 960 million KW, 2030 to 2020 demand demand 3 billion 20 million KW and 3 billion 980 million KW demand in 2050, the thermal power installed capacity accounted for decreased year by year, 2020, 2030 and 2050, the installed capacity accounted for 61%, 51% and 38%. With the deepening of the national electric power system reform and the continuous heating in the new energy field, the demand for new products is gradually increased by users. This product basically covers all areas of the middle and lower reaches of the electric power industry chain, and will be the first choice for the future power industry.

● Utility Tunnel
Guiding opinions of the general office of the State Council on promoting the construction of city underground pipe gallery (Guo Ban Fa 2015 No. 61) announced on August 10, 2015. The goal of our work is to build a batch of 2020, with the international advanced level of underground pipe gallery and put into operation, repeatedly digging the ground "road zipper" problem is obviously improved, significantly enhance the pipeline safety level and disaster prevention and mitigation, the gradual elimination of the main street spider net type overhead line, city landscape significantly improved.
