Advantage
Sandwich conductor structure
- Full-length dense, no chimney effect
- Compact structure, occupying less space in the building
- Close arrangement of conductors, overall heat dissipation, lower temperature rise
- No bending of the bus bar at the socket, high density and low impedance
- Anti-phase design to ensure correct phase sequence during installation
- The current-carrying capacity is not affected by the installation location and mounting method
Aluminum-magnesium alloy housing
- The bus bar is made of light-weight, extruded aluminum-magnesium alloy profile as the shell, with a thickness of not less than 2mm, which has high mechanical strength and can cope with various special application conditions with ease.
- The painted housing has excellent corrosion resistance and can withstand 1200 hours of salt spray testing
- With a serrated heat sink, heat dissipation area is 1.5 times the ordinary shell, heat dissipation, improve the current-carrying capacity has excellent electrical conductivity, the overall shell is not less than 50% of the phase line grounding capacity
- Aluminum alloy shell is non-magnetic environmental protection material, can effectively avoid the impact of eddy current and hysteresis loss on the busbar
Single bolt connectors
- Adopt single bolt clamping mechanism, fast and reliable installation, double the speed of traditional connectors
- Adopt double-headed fixed-torque bolts, equipped with special disc springs to greatly improve the compressive strength
- Separate temperature indicator module available to alert in case of system failure or high temperature
- Connecting bus bar cross-section is more than 1.2 times of bus bar cross-section of bus bar system, and the contact surface is double-sided lap joint, which effectively reduces the contact resistance
- Increased creepage distance by adding grooves to the edges of the insulation partition
Unique anti-phase device
The correctness of phase sequence is directly related to the operation safety of busbar system. The anti-phase device of the busbar system of Sunshine Electric can effectively eliminate the harm caused by human factors and avoid the phase sequence error.
Reliable insulation materials
- Adopt standard class B (120℃) insulation material
- Double wrapped, up to four layers between phases to ensure insulation reliability
- The insulation material is heat-resistant grade B, and the voltage resistance of a single layer can be more than 10KV, which is the professional electrical insulation material recommended by the International IEC Association.
- Non-toxic, does not produce harmful substances even at high temperatures
Reliable tap unit
- Bimetallic pin construction with silver-plated surface ensures long-lasting contact pressure and low contact resistance
- Equipped with a safety chain mechanism, plug box is not installed in place, can not close the gate, can effectively avoid plug box with load plugging
- Anti-phase design, to ensure that the plug box plugging error-free
- Plug box all live parts are effective electrical isolation, plug box installation, its ground line before the phase line and busbar system connected, plug box disconnect, ground line after disconnect
