Product Introduction

Looking for reliable voltage regulation in your 22kV distribution network? Our 22KV capacitor bank for overhead line delivers exceptional power factor correction and voltage support exactly where you need it. This specialized pole-mounted solution addresses critical challenges in medium-voltage distribution systems. Whether you're managing long rural feeders or industrial overhead lines, these units provide localized reactive power compensation that reduces technical losses and improves voltage stability. Our capacitor banks feature weather-resistant construction and intelligent switching controls designed for harsh outdoor environments.

Technical Specifications

Main Features and Advantages

Advanced Zero-Crossing Technology

Your system deserves smooth operation. Our synchronous controllers eliminate high-frequency inrush currents by switching at optimal timing points.

Comprehensive Protection Suite

Built-in surge arresters, expulsion fuses, and neutral unbalance protection ensure maximum reliability and safety for your overhead installations.

Weather-Resistant Design

Engineered for outdoor pole mounting with superior corrosion resistance and UV protection. Your investment stays protected in any climate.

Intelligent Switching Control

Automatic compensation based on real-time system conditions prevents over-compensation and maintains optimal power factor.

Maintenance-Free Operation

Vacuum switching technology and sealed capacitor construction minimize maintenance requirements and operational costs.

Practical Applications

Rural Distribution Networks

Perfect for long 22kV feeders where voltage drop affects end-users. Our 22KV capacitor bank for overhead line maintains voltage within acceptable limits without expensive substation upgrades.

Industrial Mining Operations

Heavy inductive loads from crushers and conveyors require robust power factor correction. These units prevent voltage dips during motor startups and eliminate utility penalties.

Renewable Energy Integration

Solar and wind farms connecting to 22kV grids benefit from fast-responding voltage support that stabilizes fluctuating generation profiles.

Commercial Distribution

Shopping centers and industrial parks with extensive overhead distribution systems gain improved power quality and reduced energy costs.

How It Works

Your 22KV capacitor bank for overhead line operates as a distributed reactive power source. When inductive loads create lagging power factors, the capacitor bank automatically injects leading VARs into the system.

The intelligent controller monitors voltage and power factor continuously. During peak demand, it switches capacitor steps online to boost voltage and reduce current flow. This process decreases I²R losses throughout your distribution system while improving voltage regulation.

The vacuum switching technology ensures reliable operation with minimal electrical wear. Series reactors prevent harmonic resonance in networks with non-linear loads.

FAQ

Q: How does harmonic content affect capacitor bank performance?

A: In networks with variable frequency drives, we provide detuned banks with series reactors that shift resonance frequencies away from critical harmonics, preventing overheating.

Q: What maintenance schedule should I follow?

A: Annual visual inspections are recommended, with detailed testing every 3-5 years. Vacuum switches are maintenance-free but should be checked after 2,000 operations.

Q: Can these units integrate with existing SCADA systems?

A: Yes, modern controllers support multiple communication protocols via 4G/GPRS modems for seamless integration with utility control centers.

Q: How do you control switching transients?

A: We use inrush limiting reactors and synchronous closing technology to limit transients to safe levels, typically under 100 times rated current.

Q: What causes protective fuse operation?

A: Fuses operate due to internal capacitor faults, lightning strikes exceeding arrester capacity, or severe harmonic overload. Proper coordination ensures rapid fault clearing while withstanding normal inrush currents.
