SCB13 10kV Cast Resin Dry Type Transformers Compact With IEC60076 Standards

The SC(B)13 is a high-performance, three-phase resin-cast dry-type transformer designed as a superior, fire-safe replacement for traditional oil-immersed units. Fully compliant with IEC60076 standards, it features a compact, lightweight design with low noise and loss levels. Engineered for maximum reliability in high-demand urban infrastructure, this maintenance-free solution offers exceptional mechanical strength, anti-fouling properties, and flame resistance.

• Infrastructure: Subways, airports, railway stations, tunnels, and underground power stations.
• Commercial: High-rise buildings, business centers, hospitals, and hotels.
• Industrial: Test chambers and combined transformer substations.

Our transformers feature a sophisticated monitoring system to ensure stable operation under all load conditions:

• Real-time Monitoring: PTC temperature sensors are installed at the hottest points (top of the low-voltage windings) to provide precise measurement.
• Automatic Protection: The controller triggers an Alarm Signal during overloads and an Automatic Trip if temperatures exceed safety thresholds.
• Smart Cooling: Automatically manages cooling fans based on winding temperatures to optimize energy efficiency.
• Remote Display: Supports remote temperature display and control (up to 20m for control; up to 100m with compensation conductors).

We provide high-quality protection options tailored to your installation environment:

• Material Options: Durable Stainless Steel or Aluminum Alloy.
• IP20 Rating: Prevents entry of solid foreign objects (>12mm), providing essential safety for indoor settings.
• IP23 Rating: Features rain-proof protection (up to 60° angle), making it suitable for specialized outdoor operations.

Note: Using an IP23 enclosure may affect cooling capacity by 5% to 10% depending on the unit size.

Every transformer manufactured at our facility undergoes a series of rigorous routine tests to ensure full compliance with international standards and guaranteed performance before dispatch:

1. Voltage Ratio Measurement & Vector Group Verification: Ensures the transformation ratio and phase relationship meet design specifications.

2. Winding Resistance Measurement: Checks the integrity of the conductive path and connections.

3. Insulation Resistance Test: Verifies the dielectric strength and quality of the insulation system.

4. Separate-Source Voltage Withstand Test (Applied Voltage Test): Tests the insulation between windings and to the earth.

5. Induced Overvoltage Withstand Test: Validates the turn-to-turn and layer-to-layer insulation integrity.

6. No-load Loss & No-load Current Measurement: Evaluates core performance and energy efficiency at zero load.

7. Short-circuit Impedance & Load Loss Measurement: Assesses efficiency and performance under rated load conditions.

8. Partial Discharge (PD) Measurement: A critical test for dry-type transformers to ensure long-term insulation reliability and detect any internal defects.

• 2026-Standard Modernized Manufacturing: Every JNCN transformer is born in our state-of-the-art facility, equipped with the latest German HEDRICH vacuum casting systems. By integrating automation with precision engineering, we ensure that every unit—whether cast resin or non-encapsulated—meets the highest global quality benchmarks.
• Industry-Leading Efficiency & Low Discharge: Performance is in our DNA. Our dry-type solutions are engineered to achieve ultra-low no-load losses (up to 20% better than standard ratings) and maintain partial discharge levels at ≤ 5pC to 10pC. This translates to lower operational costs and a significantly longer equipment lifespan for your grid.
• Advanced Thermal & Mechanical Resilience: Using proprietary "Airway Bar" cooling technology and high-strength glass fiber reinforcements, our transformers offer superior heat dissipation and mechanical integrity. They are built to withstand the rigors of sudden short circuits and extreme thermal cycling without cracking or degradation.
• Safety-First, Eco-Friendly Design: We prioritize human safety and environmental health. Our insulation systems (including UL-recognized NOMEX®) are flame-retardant, self-extinguishing, and non-toxic. Even under extreme heat, they produce zero smoke, making them the safest choice for high-density urban areas and sensitive industrial sites.
• Engineered for Extreme Environments: JNCN transformers are built to perform where others fail. From high-humidity coastal zones and high-altitude regions to heavily polluted industrial environments, our moisture-proof and salt-spray resistant designs ensure "immediate power-up" reliability every time.
• Global Compliance & One-Stop Service: With over 17 years of experience and a presence in 10+ countries, we understand international grid requirements. We provide a one-stop solution—from customized technical design (IEC/IEEE compliance) to seamless logistics and expert technical support—ensuring a hassle-free experience for global infrastructure partners.
