GGD low-voltage switchgear
GGD AC low-voltage distribution cabinet, fixed wiring low-voltage distribution cabinet, sub-GGD1 \ GGD2 \ GGD3, segment current capacity is different. (Hereinafter referred to as power distribution cabinet) is used in power supply, power substation, industrial enterprises and other power users, as AC 50-60Hz, rated voltage 380V, rated current up to 3150A power distribution system, as power, lighting and distribution Equipment, energy conversion, distribution and control purposes. .
Use of environmental conditions
1. Ambient temperature is not higher than +40 ℃, not lower than -5 ℃.
2. Product installation and use, the use of the altitude of not more than 2000M.
3. The ambient air relative humidity is not more than 90% (+25 ℃).
4. Equipment should be installed in the absence of severe vibration and shock, as well as the lack of electrical components subject to corrosion of the place.
5. The ambient air relative humidity at maximum temperature of 40 degrees when not more than 5%, at lower temperatures allow a greater relative temperature, should be taken into account as a result of temperature changes may occur accidentally the impact of condensation.
6. Equipment installed in the absence of severe vibration and shock, as well as the lack of electrical components subject to corrosion of the place
7. Users have special requirements can be resolved in consultation with the manufacturer
1) Rated voltage: 380V
2) Rated current: ≤ 4000A
3) rated short-circuit breaking current: 10KA, 50KA, 80KA
4) Rated short-time withstand current: 50 (1S) (KA)
5) Rated peak withstand current: 105KA
According to the use is divided into: receiving cabinet, busbar communication cabinet, feeder cabinet, motor control cabinet, reactive power compensation cabinet, lighting distribution cabinet.
Applicability, the choice of major components wide, many domestic and imported brand products can be interchangeable
Good installation flexibility, in the future even if the competent authorities to phase out certain products, because the GGD-type cabinet has a good installation flexibility, not because of the component modification or update caused by installation problems
Parts using modular standard design, with the mold installation holes, common coefficients
In accordance with the current industrial product design requirements, the use of golden ratio than the design of the partition and the size of the various parts, so that the whole cabinet nice, face a new
GGD cabinet designed to take full account of the cooling operation of the cabinet, the upper and lower ends of the cabinet have different number of cooling slots, when the cabinet electrical components heat, heat up through the top slot out. While the cold air from the bottom of the slot into the cabinet, so that the bottom of the sealed cabinet formed a natural ventilation Road, to achieve the purpose of cooling
Cabinet panel with spray technology, strong adhesion, good texture, the whole cabinet was matte tone, to avoid the glare effect, to the duty officer to create a more comfortable visual environment
The top cover of the cabinet can be dismantled when necessary to facilitate the assembly and adjustment of the main busbar on the site. The four corners of the top of the cabinet are equipped with lifting rings forLifting and shipping
The protection level of the whole cabinet is IP30, the user can also choose the IP20-IP40 according to the on-site environmental requirements.
