(2) Working condition adaptation: Custom cabinets support IP30~IP65 rating with optional anti-corrosion and fire-resistant structure; Standard boxes are only applicable to dry indoor environments with IP30 rating. (3) Intelligent function: Custom cabinets embed 4G energy consumption collection modules; Standard boxes rely on manual meter reading without communication functions.	Custom cabinets: Production lines, pump rooms, HVAC systems, fire protection facilities, photovoltaic & energy storage stations, outdoor chemical industry terminals. Standard boxes: Household PZ30 lighting boxes, ordinary offices, simple lighting circuits of small shops.	(1) Single unit equipment cost: Custom cabinets cost 15%~30% higher at base price but eliminate secondary transformation fees for separate PLC and sensor installation, cutting comprehensive expenditure by 20%. (2) Post-delivery renovation cost: Retrofitting standard boxes for linkage functions requires new drilling and wiring, doubling labor transformation cost.	Custom cabinets integrate frequency converters and soft starters to save 20%~40% power for motors; Standard boxes only adopt direct-on-line startup with high no-load loss and no energy-saving regulation functions.
Our HV & LV switchgears, box substations and intelligent complete sets; Premium international foreign-brand electrical equipment.	Equipped with identical imported components, our products are locally optimized for photovoltaic, rural power grid and salt-spray environments without expensive after-sales service fees; Foreign brands carry heavy price premiums, long lead time for non-standard customization and charge high fees for on-site commissioning.	(1) Price premium: Foreign brands charge 40%~80% higher under the same configuration. (2) Delivery cycle: 15~25 days for domestic non-standard products vs 2~3 months for foreign brands, a threefold gap. (3) On-site service fee: Free on-site commissioning by our domestic engineers vs a minimum RMB 5,000 single visit charge for foreign brand technicians.	Our products: Photovoltaic & energy storage stations, construction sites, municipal projects, Belt & Road overseas projects, large industrial parks with limited budget. Foreign brands: High-end pharmaceutical factories, precision semiconductor workshops, foreign-invested plants with mandatory brand requirements in bidding documents.	(1) Equipment procurement: Total expenditure reduced by 35%~60% under equivalent configuration. (2) Spare parts cost within 10 years: Foreign brand spare parts cost 2~3 times more with 4~8 weeks lead time; Our factory supplies spare parts off-the-shelf at affordable prices. (3) Overseas engineer dispatch: Our engineer service fee is included in project quotation; Foreign brands charge separate high fees for overseas technical support.	Our products are optimized for domestic power grid harmonic, high temperature and high altitude conditions, achieving power loss equivalent to foreign brands; Standard foreign-brand models lack adaptation to tropical and plateau environments, raising power loss by 2%~5%.
Our self-produced full product line (HV/LV switchgears, box substations, bus ducts, control boxes); Traders and small workshops only manufacturing single low-voltage cabinets or distribution boxes.	We own complete production lines with unified drawings, certifications and after-sales service; Traders assemble outsourced components with poor matching performance, scattered qualifications and cross-supplier responsibility shifting for failures.	(1) Communication coordination: Clients only need one contact person for our full set supply; traders require coordination with 3~5 suppliers, increasing communication workload by 200%. (2) Acceptance pass rate: 98% one-time acceptance rate for our uniformly designed complete sets vs over 40% rework & rectification rate for assembled solutions. (3) Delivery cycle: Synchronized delivery of full equipment within 15~25 days; Separately purchased goods from multiple suppliers face 60% higher risk of delay due to mismatched orders.	Our one-stop service: EPC general contracting projects, new energy power stations, overseas complete set export, whole industrial park power distribution projects. Single-category traders: Small shops, sporadic replenishment of tiny distribution boxes, minor renovation projects of single low-voltage circuits.	(1) Total procurement price: Volume discount for complete set bulk purchase cuts total cost by 10%~20%; Traders mark up prices through multi-level distribution. (2) Rectification & rework cost: Assembled projects generate an extra 15% hidden cost on labor and materials for adjustments. (3) Certification documents: We provide full Chinese & English certificates free of charge; Traders charge thousands of yuan separately for test reports.	Optimized matching of copper bars, protection devices and reactive power compensation ensures stable power factor above 0.95 for our integrated system; Assembled equipment suffers mismatched compensation modules with average power factor around 0.85, incurring extra power factor surcharges.
Our YB pre-installed box substations; On-site cast-in-place civil power rooms (separate compartments for high voltage, transformer and low voltage)	Box substations are factory pre-integrated, movable outdoors and equipped with built-in temperature & humidity dehumidification systems; Civil power rooms require land acquisition and civil engineering, fixed without relocation capability and poor moisture & corrosion resistance.	(1) Land occupation: 3~10㎡ for box substations vs over 50㎡ for civil rooms, occupying only 1/5~1/10 of the land area. (2) Construction period: 1 week factory pre-assembly plus 2 days on-site commissioning for box substations vs 3~6 months for civil rooms, shortening overall schedule by 85%. (3) Reusability after relocation: Box substations can be hoisted and reused for secondary projects; civil rooms are immovable and scrapped upon demolition.	Box substations: Photovoltaic power stations, temporary power supply for construction sites, road projects, residential green belts, small industrial parks with limited space. Civil power rooms: Large hub substations in urban core areas, long-term fixed large-capacity main power distribution stations.	(1) Initial comprehensive investment: The same 1250kVA box substation cuts expenditure by 30%~45% (saving land acquisition, civil construction, fire protection and duty room costs). (2) Land cost: Single station saves RMB 100,000~800,000 on land in urban areas. (3) Demolition & relocation cost: Civil rooms generate high scrapping & removal fees while box substations have zero demolition cost and recyclable value.	Box substations adopt short internal copper bars with low connection loss; Civil rooms involve multi-section cable transitions, boosting overall power distribution loss by 2%~4% with significantly higher annual power consumption loss.
Our full series bus ducts; Traditional YJV multi-core cables + cable tray radial power distribution scheme	Bus ducts adopt modular plug-in structure, fully enclosed metal housing and low-impedance rectangular copper bars; Multiple parallel cables suffer uneven current distribution, on-site cable termination required for branches and prone to insulation aging	(1) Current carrying capacity: Bus ducts carry 20%~40% higher current under the same cross-section; current deviation of cables can reach up to 15% under 2000A working condition. (2) Service life: 25~30 years for bus ducts vs 10~15 years for cables, more than double the service life gap. (3) Installation labor: Only 2 workers needed for bus duct installation while 3~4 workers for cables, labor input reduced by 40%. (4) Capacity expansion & renovation: Bus ducts support maintenance without full power cut; cables require power shutdown and disassembly, doubling construction period.	Bus ducts: IDC data centers, high-rise building shafts, large factories, main lines of photovoltaic power stations, centralized high-current power distribution. Cables: Low-power scattered terminals, short-distance branch circuits, lighting for small shops.
