How to Choose a Reliable Switchboard Factory

Switchboards are vital elements for the distribution of medium and low voltage power. Therefore, it is important to choose a reliable switchboard factory, as this affects the quality and operational safety of the product for years to come. Reliable switchboard factories offer custom solutions while alleviating the chances of low-quality materials, shoddy work, and delivery tardiness. When dealing with industrial plant construction, power distribution for commercial complexes, or developing renewable energy projects, one’s factory choice greatly influences the power system’s overall stability. The following points outline the basic criteria to assist a prospective customer in choosing the right switchboard factory.

Ensure the Switchboard Factory’s Qualifications and Certifications  

When considering a switchboard factory, one of the first things to evaluate is the qualifications and certifications. These demonstrate adherence to international and national benchmarks, including the factory’s compliance with various industry standards. A switchboard factory is qualified and should hold the following core certifications: IEC (International Electrotechnical Commission) standards (e.g. IEC 62271 for switchgear), ISO 9001 (quality management system), ISO 14001 (environmental management system), and OHSAS 18001 (occupational health and safety management system). These show that the factory has consistent production and effective quality control systematic processes for the switchboard. Also, for regional markets, the factory should have local certifications--CE for the European market, UL for North America, and CCC for the Chinese market--which show that the switchboards meet local electrical safety regulations. Take for example a switchboard factory supplying products to industrial projects in Europe. Such a factory must have CE certification as it is proof that the switchboards meet the European Union’s safety and electromagnetic compatibility requirements. Business licenses, production permits, and project experience certificates must also be checked, as in cooperation with large power companies or infrastructure projects, as it helps to ensure legal operation qualifications and practical industry experience are held.

Capacity and Technical Strength of the Production Switchboard Factory

When determining whether a switchboard factory is reliable, the production capacity and Technical Strength should sustain large-batch orders and customized requirements. Production capacity can be assessed by the factory's production scale. This includes the workshop a switchboard factory should have production area, the number of production lines, and the yearly output. Advanced facilities like CNC punching machines, laser cutting machines, and automated assembly lines should be available along with sufficient production lines dedicated to the different types of switchboards like MNS switchboards, GGD switchboards, and ring main unit switchboards. These will help keep the precision and quality of the components such as the cabinet body, busbar, and switchboard as a whole. Regarding Technical Strength, the factory’s Research and Development Team can be evaluated by the number of engineers, years of experience, and capabilities to design switchgear and customizations. A factory should be capable to design and test custom switchboards with special functions like intelligent monitoring and adaptation to high altitudes, for projects requiring such functionality. Technical documents like product design drawings, test reports, etc. can prove the factory's competency in switchboard technology.**Examine the Quality Control system of a Switchboard Factory**

Having a robust system of quality control is a hallmark of a dependable switchboard factory. It is an essential indicator of the safety and durability of the switchboards. When assessing a switchboard factory, ask for the process control systems which encompass quality management from the oversight of raw materials to the examination of the end products. To begin, inspect the factory’s system of procuring raw materials: a dependable switchboard factory must acquire materials from reputable providers (for instance, copper busbars from certified metal manufacturers and insulating materials from certified chemical manufacturers) and perform adequate control of quality incoming inspections (such as testing the conductivity of copper and the insulating potential of epoxy resin) during the incoming inspections. To continue, evaluate the factory's quality control system during production: while the assembly process is taking place, the factory is to have dedicated inspectors for the particular control points, which include busbar connection torque and module alignment, and utilize specific tools to confirm controls, for instance torque wrenches and insulation testers, to enforce the standards.

Third, ascertain the factory’s capabilities regarding the testing of finished products: reputable switchboard manufacturers should have factory-installed testing capabilities, including a testing lab with instruments for electrical performance testing (e.g., AC withstand voltage testing, partial discharge testing), mechanical performance testing (e.g., operation cycle testing), and environmental adaptability testing (e.g., high ambient temperature, high humidity). Each switchboard should be subjected to a 100% partial discharge test to guarantee the absence of insulation defects prior to leaving the factory. You have the option to visit the factory site and lab to witness the quality assurance procedures.

Evaluating After-Sales Services and Project Cases from a Switchboard Factory

Quality and reliability are key factors when deciding on a switchboard factory. Besides quality products, a switchboard factory should also provide continuous after-sales service throughout a switchboard’s lifetime. When selecting a switchboard factory, ask about their after-sales service agreement, which may include on-site inspections during the warranty period, maintenance checks, and the availability of spare parts. Warranty service maintenance should also address service calls within a predetermined time (e.g., within a 24-hour window). For instance, warranty service maintenance should provide post-installation service to ensure the switchboard operates correctly during warranty maintenance service. Furthermore, consider the factory’s project experience. A factory that has extensive experience with project types similar to yours (e.g., solar power stations, industrial plants, commercial malls) will likely understand your requirements better and offer more appropriate solutions. For example, a switchboard factory that serves the food processing sector in your area should understand moisture-proofing and anti-corrosive switchboard requirements. This will also provide a basis for estimating their ability to meet project timelines and manage challenges that may arise.

Consider the Reputation and Customer Feedback of the Switchboard Factory  

A switchboard factory’s reputation within the industry as well as the feedback received from current customers are crucial indicators of the factory’s reliability. Many customers as well as prospective clients tend to gauge the reputation of a switchboard factory by its standing within the industry and the awards received, such as, “Top 10 Switchgear Manufacturers”, etc., or even coverage in press. One may assess the feedback received from customers by getting in touch with the factory’s past customers as authorized by the factory. Product quality, delivery, and after-sales service are vital areas of customer feedback. Feedback, both positive and negative, of customers on industry forums or on switchboard factory rated B2B contacts may prove useful, though one should be cautious about user feedback geared towards promotion. Take note of the instances when customers say factory products have suitable after sales service or when customers remark that products have low failure rates. Also check the duration of relationships with customers. Clients should ideally expose a long relationship with the factory before being counted as satisfied.  A switchboard factory should not have a reputation of unresolved complaints, of any kind. This eases procurement issues.
