[Chai Jin cable tray to recommend the star product - bridge] According to the construction of the main functional requirements to determine its grade and content, these systems include different types of cables and wires, some of which belong to active cables (power supply voltage is typically DC12 / 24 / 48V and AC220V), Cascade cable bridge, the construction industry due to the constant development of cable bridge is also advancing with the times and continue to be recognized and accepted by the market localization efforts cable tray industry, product selection of high-quality cold-rolled steel, received extensive attention selection of quality cold-rolled steel, surface technology cold galvanizing, hot dip galvanized, electrostatic spraying, fire retardant paint, paint. Which products are widely used in petrochemical, metallurgy, Linfen cable bridge, electricity, schools communications, high-rise building, has a beautiful appearance, corrosion resistance, versatility extensive installation flexibility, range and other characteristics. The spirit of "quality first, reputation for heavy, management-oriented, sincere service" purposes. [Chai Jin cable tray to recommend the star product - as long as the bridge] Combined cable tray with wide 100,150,200mm three groups based on what you need can be composed of foot cable tray (20) inch cable bridge, it without the production of elbow, tee and other accessories can be installed at the scene of any steering, widened the points lead, lead down. At any site, no drilling, welding pipe can be drawn. It can facilitate the engineering design, manufacture and convenient transportation, more convenient installation and construction, is currently the best in cable tray products. [Chai Jin cable tray to recommend the star product - bridge] how to learn from a given deflection deflection, trough cable bridge, also no clear provisions in the area clearly should consider reducing the burden around the degree, which means that the amount of steel will increase accordingly, so that cable tray factory, as long as the full use of the calculation of the maximum allowable stress of steel, and to ensure adequate safety coefficient, the maximum deflection of the span (anchor pitch) than take 1/250 ~ 1/150 appropriate. Expansion contraction issues. Fireproof cable tray | Chai Jin cable tray | cable tray Linfen Chai Jin from the Tianjin cable bridge Limited. Chai Jin Tianjin Cable Bridge Co., Ltd.
