Ⅶ. FAQ – Common Questions
Q1: Which type of Box type substation is more suitable for short-term road construction sites?
A: For short-term projects or sites that require frequent relocation, such as roads and bridges, a mobile box-type substation compatible with trailers is preferred. For large construction projects lasting more than six months, an outdoor reinforced European-style Box type substation can be chosen.
Q2: Can Box type substations be dustproofed in mining environments with high dust?
A: Yes, mining-specific models improve overall dust-proof sealing, and internal components are selected for dust resistance to reduce the likelihood of faults caused by dust accumulation.
Q3: Can Box type substations be specially modified for outdoor sites in low-temperature or rainy areas?
A: In low-temperature environments, internal heaters can be added. For rainy areas, the box’s waterproof structure can be optimized. Coastal mining sites can have extra anti-corrosion coating. All modifications can come with written documentation.
Q4: Are all necessary equipment documents provided for site entry registration?
A: Yes, we can provide equipment test reports and the company’s operating qualifications. Documents are formatted to meet entry and bidding registration requirements for various construction projects.
Q5: How long does it take to repair a power outage at a construction site Box type substation?
A: For domestic sites, workers can be arranged nearby for on-site service. For overseas projects, real-time online technical guidance and fast shipping of spare parts are available. Each component of the equipment has an independent warranty period.
Q6: Can Box type substations purchased for overseas construction sites be adapted to local power standards?
A: Yes, equipment can be adjusted according to local voltage and frequency standards. Complete export documentation is provided, along with multilingual operation manuals.
Q7: If additional construction machinery is added later, can the original Box type substation be expanded?
A: The box uses a modular structure, allowing transformers to be replaced and low-voltage circuits increased without replacing the entire unit. On-site surveys can be conducted to provide an expansion plan.
Q8: What basic information is needed when purchasing a site-specific Box type substation?
A: Information required includes the total site power load, voltage requirements, construction period, whether frequent relocation is needed, site environment (dust/rain/low temperature/coastal), and local power entry requirements. Staff will then match the appropriate box type substation model accordingly.
