The BSM6 series high-voltage common box busway is specially developed for 6KV-35/40.5KV power systems, with a protection level of IP54, suitable for indoor environments. Compared with ordinary common box busways, it has the advantages of anti resonance and good heat dissipation. Used for electrical connections between high-voltage transformers and high-voltage power generation panels, as well as between generator sets and impulse transformers.
Installaton way: The busbar is suitable for outdoor installation, it owns
rain proof and wind resistance structure，the installation and maintenance.
hole is always upward in general situation,it is required to report to the manufacturer when it is installed downward. The busbar is suitable for the electrical connection between high-voltage transformer and high-voltage generator panel as betwee geerator unit and voltage leading transformer.
Power distribution way: Three- phase-th ree-wi re, neutral -point unearthing
power suppy system of 10KV or below.
Rated voltage:3.45KV-35KV
Rated current:3.45KV-11.5V/400A-5000A 35KV/100A-1000A.
Rated power:50Hz
Box:The steel plate with weak magnetism and alumium alloy are used as box
shell.
Earthing protection system:in line with the requirements of IEC-364-5-54 system.
Protective gradeandoor installation type: IP40.Outdoor installation type:P54
Load performance: The temperature rise of conductor and shell in rated
current is in line with temperature rise requirements of GB763-74 of AC high-voltage electrca I appliances in long -term operation.
Short-circuit performance:The dynamic stability test and thermal stability
test are in line with AC high-voltage electrical appliance test method and GB-2706-81 standard.
Insulation performance: In line with GB311.1-83 standard
The destruction一resistant insulator in different grades can be selected in design according to the short-circuit capacity of power supply system and the common destruction-resistance force for the insulator can be classified into 400kg,800kg and 600kg.
