CFW-3A high-strength Busway closed
Sitepath：Home > Products > Electrical > Busway
The scope of application of
CFW-3A high-strength for the exchange of closed bus three-phase four-line, three-phase five-wire system, the frequency of 50v ~ 60Hz, rated voltage to 660V, rated operating current of 200 ~ 4000A for transmission power distribution system used.
1, the structural characteristics
Suitable for the installation of large span
Busway in the series are small, compact structure, shell molding machine using roll-shaped cross section into a corrugated profile, which greatly increased its load capacity, so that it will have the support of extraordinary strength, we can make sure to connect the Center 6m bus load 70kg, deflection not more than 15mm, to solve a large span of places can not support the installation of lifting problems.
1m length busbar can be set up in two jack, two set up to four, without affecting the strength of their support.
Convenient and quick to install
a, because the design of large span, so the installation of supporting small, small number of joints can be substantial increase in installation speed.
b, the use of butt-type joints, the connection will be connected only to insert copper connectors, bolts can be tightened further;
c, small size, light weight, easy to install.
Good heat dissipation for high-current transmission,strong
a, bellows-type cover plate in the plate-fin heat played a role in increasing the cooling area, the small thermal resistance, thermal speed, lower temperature rise of copper.
b, the use of double-lap joints, so that copper busbar lap joint double the area increase, reduce the contact resistance and temperature rise joints.
A high degree of standardization
Busbar trunking system for all current levels of cover are unified, standardized high degree of exchange capacity, convenient interface varactor.
2. Main technical parameters
Busway in line with the performance of IEC439-2, GB7251.2-1997.
Busway to 110% rated current and rated voltage of the long-term work.
Busway housing profiles used roll assembly, conductive emission current density of the use of economic, so that it can withstand the strong electric stress and thermal stress. According to Table (1) data through the dynamic thermal stability test, and test bus was the permanent deformation can not be detected.
Multi-layer conductive coating row busbar insulating materials, can withstand the power frequency withstand voltage of 3750V, which lasted 1min without breakdown and flashover.
In the ambient air temperature of 20 ± 5 ℃, relative humidity of 50 ~ 70% of the normal section of each of its insulation resistance of not less than 20MΩ.
Busway in the long term through the rated current, the conductive parts of the temperature rise of less than Table (2) ＆#118alues listed in:
Busway closed structure using high-strength, protective levels of up to IP40.
Busway Busway plug the plug case and the number of not less than 200.
Busbar cross-section dimension and see the weight per meter (1) and Table (3).

CFW-3A high-strength due to the closure Busway unique design style, reasonable structure, it sets the advantages of air-based and-intensive in the same, and products in the domestic Busway unique. Significant because of their superior mechanical properties and electrical performance, it is widely used in electric power, petroleum, chemical, transport, civil aviation and other modern high-rise buildings, large-scale plants, substations, power plants and other places of power distribution room, basement, Kennedy Well laying paragraph.
