RAM 1250V 3000KVar 1000Hz Electric Heating Capacitor

Designed for high-frequency, high-power electric heating systems. Supports reactive power compensation, line loss reduction, and power quality optimization across electric furnace and induction heating applications.

Product Overview

The RAM series delivers rated voltage of 1250 V with reactive power capacity of 3000 kvar at 1000 Hz, supporting high-frequency electric heating applications requiring precision and efficiency.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. The design incorporates high energy density and low loss characteristics, contributing to improved production efficiency while reducing maintenance costs. The capacitor operates stably at 1250 V, demonstrating voltage withstand performance and long-term reliability in industrial environments. Advanced materials and precision manufacturing processes ensure stable operation under working conditions, effectively improving the system's reactive power compensation capability.

Three configuration options are available to accommodate different system requirements: single cooled-live case design with sub-sections (one terminal connected to casing), single cooled-isolated case design with sub-sections (all terminals isolated), and double cooled-isolated case design without sub-sections (all terminals isolated). This flexibility allows integration with various system grounding requirements and thermal management approaches.

Frequently Asked Questions

What is the difference between live case and isolated case configurations? +

In live case configuration, one terminal is internally connected to the capacitor casing, requiring the casing to be grounded. This design is typically used in systems where the capacitor is part of a grounded circuit. In isolated case configuration, all terminals are isolated from the casing, providing flexibility for floating or ungrounded system designs.

What is the difference between single cooled and double cooled configurations? +

Single cooled configuration uses one cooling system and includes sub-sections for internal fault isolation. Double cooled configuration provides enhanced thermal management with two independent cooling systems and no sub-sections, suitable for higher power applications requiring maximum heat dissipation capacity.

What does the "S" designation in the model number indicate? +

The "S" indicates single cooled configuration with sub-sections. This means the capacitor has internal sub-divisions for fault isolation and uses a single cooling system. "D" indicates double cooled configuration without sub-sections, providing enhanced cooling for higher power applications.

What is the expected service life under continuous operation? +

Service life is influenced by operating temperature, voltage stress, and duty cycle. Under rated conditions with proper cooling, the design life exceeds 80,000 hours. Regular monitoring of capacitance and dissipation factor is recommended to track degradation.

How does this capacitor improve electric heating efficiency? +

The 3000 kvar reactive power capacity provides sufficient reactive power compensation, effectively reducing line losses and optimizing power quality. This results in improved electric heating efficiency, reduced operating costs, and enhanced system performance for high-frequency heating applications.
