Yunnan ladder bridge and yunnan trough bridge difference
Groove bridge is a bridge in yunnan industry the most commonly used models, fully sealed, like the box shape, dustproof, strong anti-jamming capability, high protective carrying cable less susceptible to serious corrosion damage, often used in the construction industry, simple structure, protective performance is strong, good load capacity, so is the most popular model bridge industry, Generally used for laying data control cables, communication signal cables and so on.
Yunnan ladder type bridge appearance is unique, like a ladder shape, but its bearing capacity is stronger than the groove type, tray type bridge, because it is the middle welding bar reinforcement, laying cable in the trunk, unique appearance makes it lighter in weight, heat dissipation good ventilation performance, convenient and better installation and construction personnel, and security is also very high, when there is damage to the circuit leads to failure, Maintenance personnel can also clearly find out the problem line using the corresponding safety measures, so that the product has become the new focus of the bridge industry, often used for laying large diameter cables, high and low voltage power cables, power cables and so on.
Conclusion: groove bridge and ladder type bridge each have each advantage, according to different environment design, better to each cable laying, when the cable is not much, can also be different grade laying cable rack at the same bridge, contact the manufacturer will bridge with partition, with partition to distinguish between different levels of cable isolation, reduce cost and their operation. If the construction environment with high corrosion and high fire protection requirements is encountered, corresponding measures can be taken for the bridge. Usually, the bridge is made of cold rolled sheet, and the surface treatment is carried out. Hot dip galvanized (hot dip zinc), fire paint, electric galvanized, electrostatic spraying, targeted protection or use better original plate manufacturing: stainless steel, aluminum alloy, glass fiber reinforced plastic.
