SMC Double Doors Distribution Cabinet with Window




The box body is made of glass fiber-reinforced unsaturated polyester material (SMC) by high-temperature molding. The whole box body is assembled by the environmental buckle of each functional component, and the manufacturing precision is high. Its structure is novel, compact, easy to assemble, and has unique design features of waterproofing and ventilation.


  1. The lock is made of high-energy materials, with exquisite appearance, and better anti-corrosion and anti-leakage performance than other locks.
  2. The support shaft of the lock has better stability and is made of insulating materials with better insulation performance, and can be easily combined, disassembled, and installed.
  3. The cabinet can be combined according to the needs of the site environment and can be installed with a one-story base, a second-story base, or a channel steel base.
  4. Perspective windows can be customized according to the needs of the box configuration. The window edge is made of anti-ultraviolet and aging-resistant PC materials. The product has better transparency, visibility, waterproof, dustproof, and impact resistance.
  5. A single-layer or double-layer suspension spreader can be installed above the box for high-altitude suspension and fastening.
  6. The cabinet has two colors white and army green for customers to choose from.



Product advantages


Effective waterproof, dustproof, anti-condensation, anti-condensation frost.

Excellent outdoor protection level, up to IP65.

Modular building block structure, lightweight, easy installation.

Streamlined shape, anti-sticking, in line with environmental protection requirements.

The door lock and latch are non-metallic, 100 % insulated, the door opening angle is 180 °, and the replacement of the door and moving parts does not require tools.

The overall structure is stable, padlocks can be added, and the windows are impact-resistant, preventing behaviors such as stealing electricity, and are safe and reliable.





LW series low-voltage branch boxes and integrated power distribution cabinets are used for power distribution and control of power, lighting, and power distribution equipment in power systems with rated frequency 50/60HZ and rated voltage 220V/380V/660V. The box body is made of SMC glass fiber-reinforced polyester material. It has many advantages such as environmental protection, beauty, no light pollution, strong insulation, chemical corrosion resistance, flame retardant and heat insulation, and good toughness. It is the first choice for various power distribution projects.



Application range


The products are suitable for various harsh environments, substations, industrial and mining enterprises, urban roads, garden residential quarters, high-rise buildings, airports, and other outdoor public places. It is especially suitable for use in factories with corrosive gases such as petroleum and chemical industries, as well as places with high salt spray such as coastal areas and islands.



Performance characteristics


The box has good electrical performance. Insulation index, dielectric strength, tracking resistance index, aging resistance index. Even in a very humid and harsh environment, there will be no condensation or other phenomena, and it has very strong mechanical strength. It has the unparalleled safety performance of the metal box. Even if the internal circuit of the box fails and is damaged by external impact, it will not cause damage. The box is live, especially suitable for use in densely populated areas.


Chemical corrosion resistance: good corrosion resistance, can resist concentrated acid, alkali, and salt corrosion, and has good resistance to various oils, organic solvents, and seawater.


Strong anti-aging performance: good anti-aging performance, the surface of the cabinet is also coated with a layer of protective paint with strong UV resistance, the double protection makes the cabinet have higher anti-aging performance.


Strong insulation performance: excellent insulation material, good surface resistance, volume resistance, breakdown voltage level, and can maintain good dielectric properties at high frequencies, not affected by electromagnetic effects, and does not reflect electromagnetic waves.


Good temperature resistance: the material can still maintain good physical and mechanical properties at a wide temperature (-50C~+160C)


Good thermal insulation performance: thermal insulation can reduce the influence of ambient temperature difference on the internal temperature of the cabinet, effectively reducing condensation and frost inside the cabinet. Good flame retardant performance: the combustion resistance can reach FVO level. The smoke density level is 15, and the smoke toxicity level is quasi-safety level one (ZA1).


Lightweight, high strength, and toughness: The ratio is between 1.75 and 1.95. It has high tensile strength, bending strength, and impact toughness. Its strength and toughness (the value of material strength divided by density) can be compared with high alloys.


No notch sensitivity: the three-dimensional network structure has good concave resistance, is not sensitive to notches, does not produce neat fractures, and fractures do not spread.
