The JDJJ(F)2 transformer is meticulously designed to meet the rigorous demands of modern electrical grids. Key features include:

Enhanced Insulation System: Utilizes advanced oil-paper insulation materials and structural design, significantly improving dielectric strength and resistance to thermal aging, ensuring long-term operational safety in 35KV applications.
Optimized Magnetic Core: Features high-grade, low-loss silicon steel laminations with step-lap core construction, effectively minimizing no-load losses and noise levels for greater energy efficiency and reduced environmental impact.
Robust Tank Construction: Fabricated from high-quality steel with superior corrosion protection, the tank ensures mechanical integrity and longevity, even in challenging environmental conditions. Sealed design minimizes maintenance needs.
Intelligent Protection & Monitoring (Optional): Can be equipped with Buchholz relays, pressure relief devices, winding temperature indicators (WTI), and oil temperature indicators (OTI) for comprehensive fault detection and operational oversight.
Flexible Configuration: Available in various standard ratings and tap changer options (off-circuit or on-load tap changers available upon request) to match specific grid voltage regulation requirements.

Below are key technical specifications for standard models (Custom specifications available):

Parameter	Value / Description
Rated High Voltage (HV)	35 kV (Standard)
Rated Low Voltage (LV)	0.4kV, 6.3kV, 10.5kV, 11kV, 33kV (Common Options)
Frequency	50Hz or 60Hz
Vector Group	Dyn11, Yyn0, YNd11, etc. (Customizable)
Insulation Level (LI/AC)	200/85 kV (Typical for 35KV class)
On-load Tap Changer (OLTC)	Optional, typically ±8x1.25% or ±10x1.0%
Standard	IEC 60076, GB 1094 (Equivalent)

Choosing the JDJJ(F)2 translates into tangible benefits for your operations:

Reduced Lifetime Cost: The combination of low guaranteed losses (No-load & Load), high efficiency, and minimal maintenance requirements significantly lowers the total cost of ownership over the transformer's extended lifespan.
Unmatched Operational Security: The comprehensive 10-year warranty provides financial peace of mind, while our responsive global technical support network ensures expert assistance is available for troubleshooting, maintenance advice, or spare parts, minimizing downtime risks.
Proven Grid Stability: Rigorous design, quality materials, and strict manufacturing controls under ISO9001 ensure stable voltage transformation, high short-circuit withstand capability, and reliable performance critical for uninterrupted power supply.
Global Compliance & Adaptability: Designed to meet international standards (IEC) and adaptable to regional specifications, facilitating seamless integration into diverse power systems worldwide. Ports like Shanghai, Tianjin, Guangzhou, and Ningbo ensure efficient logistics.
