How to upgrade your outdoor electric control cabinet?

The electrical control cabinet is a control cabinet (box) assembled with switchgear, measuring instruments, protective appliances and auxiliary equipment according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, be convenient for maintenance and not endanger the safety of people and surrounding equipment. Including (distribution cabinet) (distribution box) (electrical control cabinet) and so on. During normal operation, the circuit can be turned on or off by manual or automatic switch. When there is a fault or abnormal operation, cut off the circuit or give an alarm with the help of the protection device. Through measuring instruments, various parameters in operation can be displayed, and some electrical parameters can be adjusted to prompt or signal deviations from normal working conditions. Electrical control cabinets are often used in power generation, distribution and substation. At present, the outdoor control cabinet of outdoor electric control cabinet generally adopts metal control cabinet. There are several problems in the long-term use of outdoor control cabinet of metal cabinet: (1), self-conduction, potential safety hazard; (2) poor corrosion resistance and short service life; (3) The box is seriously stolen, which threatens the safety of the company and increases the use cost; 4), serious corrosion, the coating is easy to peel off, which seriously affects the beautiful environment. Non-metallic SMC FRP composite control cabinet is a new type of FRP composite outdoor control cabinet developed by Ningbo Huayuan according to market demand. It is the best substitute for traditional metal control cabinets, especially suitable for outdoor control cabinets with high requirements. Non-metallic SMC FRP composite control cabinet has the following advantages: strong anti-aging ability and service life of 30 years; Do not rust, do not need to regularly apply antirust paint for maintenance, so maintenance-free; Strong anti-pollution ability, can be used in places with high salt concentration, such as seaside and places with high pollution degree, and is not easy to discharge along the surface; Strong impact resistance, not easy to damage; Non-metallic material, so it will not be stolen, beautify the environment and have good social effect; Non-metallic materials have good insulation performance and are not easy to cause electric shock or leakage accidents. The shell of nonmetallic SMC FRP composite control cabinet is produced by SMC composite molding process. SMC composite is a kind of sheet fiber reinforced thermosetting composite. SMC composite material is a fiber-reinforced thermosetting composite material wrapped in upper and lower plastic films by polyester resin, chopped glass fiber, filler and auxiliary materials. The application of glass fiber reinforced plastic composite SMC composite material in electrical control cabinet has the following advantages: 1, good electrical performance. The fiber-reinforced polyester Ningbo Huayuan SMC composite used for manufacturing electrical products has the following electrical properties: insulation resistance (soaked for 24 hours): 1.0x 1m? Arc resistance: 180s proofing tracking index:? 600v insulation protection and creepage resistance meet DIN/VDE standards. This material not only has excellent electrical insulation, but also maintains good dielectric properties at high frequency, which is not affected by electromagnetic action and does not reflect electromagnetic waves. These properties are far comparable to those of nonmetallic materials. 2. Chemical corrosion-resistant fiber reinforced polyester Ningbo Huayuan SMC composite has good corrosion resistance to acid, dilute alkali, salt, organic solvent and seawater, while metal materials are not resistant to acid and seawater. 3. The specific strength and modulus of light weight and high strength are one of the indexes to measure the bearing capacity of materials. The specific modulus of fiber reinforced polyester SMC composites is equivalent to that of steel, but the specific strength can reach 4 times that of steel. 4. The tensile strength of fiber reinforced polyester Ningbo Huayuan SMC composite is slightly better than that of steel. The fatigue limit of steel and most metal materials is 40%-50% of their tensile strength, while the fatigue limit of fiber reinforced composites is generally higher than this value, up to 70%-80%. 5. Notch sensitivity When the element is overloaded and a few optical fibers break, the load is quickly distributed on the undamaged optical fibers, and the mechanical balance is achieved again. This is unmatched by metal parts. 6. Low thermal conductivity and low expansion coefficient. When there is a temperature difference, the thermal stress is much smaller than that of metal. 7. Excellent ultraviolet resistance and aging resistance Among nonmetallic materials, fiber-reinforced polyester SMC composites have excellent aging resistance. The test of anti-aging performance shows that the maximum aging thickness of its surface in 20 years is less than 50 in different places and different climatic zones. M the minimum thickness of most boxes is 5mm, which is less than 1% of the box thickness, so it has no obvious influence on the mechanical properties of the box. Our company has adopted a special anti-ultraviolet surface treatment process to further strengthen its anti-aging performance. 8. Long service life The service history of Europe can prove that its service life is at least 20 years; The simulated aging test shows that its service life is more than 20 years, far exceeding that of traditional materials such as metals. 9. Flame retardant, smokeless and nontoxic. This material is a kind of flame retardant material, the flame retardant grade is FV0 (the highest grade of nonmetallic materials), the smoke grade is 15 (smoke grade is 1 grade 100) when burning at high temperature, and the smoke is non-toxic and the toxicity grade is ZA 1 (quasi-safety grade). Ningbo Huayuan can use this material to make box modules with different shapes through molding process. SMC outdoor control cabinet assembled by SMC box module is applied to outdoor control equipment manufacturing industry, replacing metal control box equipment widely used in outdoor control equipment manufacturing industry at present. Ningbo Huayuan supplies all kinds of SMC control cabinets. Ningbo Huayuan Group was established in 1994, located in Gao Qiao, the hometown of Liang Zhu. Is a set of material production, mold making, parts molding as one of the glass fiber reinforced plastic professional group company. The company has long been committed to the production of SMC/BMC materials. SMC/BMC molding and BMC injection molding services, as well as the strong technical force and strong technical research and development capabilities of SMC/BMC Mould Design and Manufacturing Group Composite Branch, can provide customers with integrated solutions for SMC/BMC composites. The annual production capacity of SMC/BMC composites reaches 25,000 tons, and the SMC and BMC materials produced by the company have passed UL and SGS certification. GRP GRP Products Branch has more than 60 SMC/BMC GRP professional molding machines,100t-2,500t, with an annual pressing capacity of 5 million pieces. In SMC/BMC electrical, automotive, rail transit, construction and other industries to provide customers with SMC/BMC molding products processing services. We have established long-term cooperative partnerships with world-renowned enterprises such as American GM, Germany Siemens and South Korea LG for many years. The group company has developed a series of FRP products such as SMC composite cable bracket, BMC composite insulator and SMC composite box, such as SMC optical cable junction box, SMC multimedia box, SMC distribution box, SMC cable branch box, SMC traffic signal control box, SMC water meter box and so on.
