Read the supplied description before sharing project requirements.
Efficient powersystem construction relies on energysaving, ecofriendly and highly reliable core powerdistribution equipment. We manufacture the Jinma SGB13 nonencapsulated drytype transformer. Built around a nonencapsulated dryinsulation structure, it delivers energy efficiency, compact footprint and enhanced safety. It is engineered for confinedspace indoor urban powerdistribution scenarios, perfectly matching power demands in core city zones, rail transit, commercial complexes and other indoor facilities. Compliant with national energyefficiency and environmental standards, it follows market trends for drytype distribution transformers and serves as preferred equipment for indoor safe power supply and urbangrid upgrading.
Our Jinma SGB13 10 kV nonencapsulated drytype transformer is energysaving and safetyoriented distribution equipment developed for urban indoor powerdistribution applications. It adopts Hclass insulated nonencapsulated windings and an oilfree drytype structure, combining fireproof, explosionproof, lowloss and maintenancefree merits. It works as an ideal alternative to conventional oilimmersed transformers.
At its core is the nonencapsulated drytype design featuring highefficiency energysaving performance. There is zero risk of oil leakage for safer indoor installation, which greatly simplifies fireprotection requirements for distribution rooms. Hclass insulation plus lowloss design enables higher energysaving performance and stable operation, wellsuited for complex urban indoor powerdistribution environments. Strictly complying with national energysaving and environmentalprotection standards with zero pollutant emissions, it fits global greenpowerconstruction requirements. Widely deployed for urban indoor substations, railtransit power supply, commercial complexes and highrise buildings, it keeps seeing rising market demand.

02 / FEATURES
Capabilities described in the source.
Nonencapsulated drycore structure
We adopt nonepoxyresin encapsulated winding construction with excellent heatdissipation capacity. It avoids cracking risks of casting encapsulation layers and delivers stable longterm insulation performance, supporting continuous fullload equipment operation.
Hclass high energy efficiency
The SG(B)13 series follows national Grade1 energyefficiency standards. Both noload loss and load loss are substantially lower than conventional products. Outstanding energysaving performance cuts electricity costs over longtime operation.
Fireproof, explosionproof and ecosafe
Oilfree drytype design delivers noncombustible, nonexplosive performance without leakagecaused pollution. No oil tank or auxiliary firefighting facilities are required. It fits indoor powerdistribution in corecity and denselypopulated zones and meets greenenvironmentalprotection requirements.
Strong shortcircuit resistance & environmental adaptability
Robust winding mechanical strength brings superior shortcircuitshock withstand capability. It copes with complex indoor conditions including high humidity, heavy dust and high altitude, performing anticondensation and anticorrosion for stable and reliable operation.
Intelligent upgrade ready
It supports online temperature monitoring plus remote fault alarm functions. Seamless connection with intelligent powerdistribution systems satisfies smartupgrading demands for urban power grids and boosts powerdistributionmanagement efficiency.
Maintenancefree longcycle operation
Thanks to nonencapsulated drytype sealing design, regular oil replacement, oil filtering and oilquality testing are eliminated. Simplified operation & maintenance workflows greatly reduce OPEX and operational difficulties for urban indoor powerdistribution projects.
