Cable trays are divided into: trough, tray and ladder, net format and other structures, consisting of br. TrunkingThe trunking is divided into: insulated wiring trough, split wiring trough, mini wiring trough, separate wiring trough, interior wiring trough, integrated insulated wiring trough, telephone wi. The bridge frame is a general term for a system of continuous rigid structures for supporting cables by straight lines of trays, ladder frames, bends, attachments, and supports and hangers.
Cable trays are divided into trough-type cable trays, tray-type cable trays, stepped cable trays, and grid trays. They are composed of brackets, support arms, and installation accessories. It can be erected independently or laid on various buildings structures and pipe racks. It reflects the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance.
All parts need to be galvanized and installed in the building If the bridge frame outside the open air is near the seaside or belongs to a corrosive area, the material must have the physical characteristics of corrosion resistance, moisture resistance, good adhesion, and high impact resistance. Shanghai Richeng Electronics Co.
Mobile WebSite. According to JGJ But the bridge is stronger than the trunking, more used to put the cable, of course, you can discharge lines, usually strong power system. This is due to the installation of different height due to the installation of a low height must have a cover, a bad heat dissipation, filling rate will be smaller.
Metal wire slot seal better, not necessarily support the support, can be laid in the cable trench and the construction of mezzanine. Some of the trough bridge is semi-open type, there must be a bracket to support, in the house or outside the building generally erected. Bridge is mainly used for laying power cables and control cables, the lower the strength of the trunking, usually used to lay wire and communication cables, such as Internet telephony.
Bridge bending radius is relatively large, most of the right angle groove bend. Bridge span is relatively large, smaller trunking. Therefore, a large difference between the fixed bracket, hanger the number of large differences.
Cable tray is system wiring in the building in which electrical insulated wires are used to distribute power and communication to various access points while Cable trunks are power supply lines that are used to distribute power and communication to large areas like industrial city.
Cable tray is a ladder-open-type use in wiring system can be use in outdoor or indoor with option of a cover or not covered. While the cable trunk is close type use in wiring system can be plastic or metal. Use in indoor place specially in panel boards for plastic.
And for metal can be used as multiple homerun circuit that a conduit can not be use. Per the National Electrical Code, a cable tray system is "a unit or assembly of units or sections and associated fittings forming a rigid structural system used to securely fasten or support cables and raceways.
Cable Trunk-A trunk often consists of multiple wires, cables , or fiber optic strands to maximize the available bandwidth and the number of channels that can be accommodated. A trunk can also be a broadband wireless link. The use and management of trunks in a communications system is known as trunking.
Cables are exposed and easily accessible — making inspection and future modifications uncomplicated. These solutions require minimal space. Cable ladders are typically supplied in 3 or 6-meter lengths. Cable tray Other common names: trough, ventilated cable tray Consists of a single sheet of metal. Many cable trays have slot patterns, which makes it easy to position equipment and fasten cable ties and other fixings, such as tubing clamps. Suited for light electrical and instrumentation cables and tubing.
The bottom coverage helps reduce electromagnetic interference, while the perforations enable water drainage and ventilation. Cable trays are the most aesthetically pleasing option. In buildings with no panelled ceiling, cable trays can be a great option for hiding cables whilst keeping them organised. Cable trays are typically supplied in 3-meter lengths. Contact us.
