Mounting Frame/Enclosure: Weight Capacity 50-500kg

Component Specifications

Definition

A mounting frame/enclosure is a structural component designed to securely house, support, and protect capacitor bank units in electrical systems. It provides mechanical stability, facilitates proper installation and maintenance access, and ensures safety by preventing accidental contact with live components while offering environmental protection against dust, moisture, and physical damage.

Working Principle

The mounting frame provides rigid structural support to maintain capacitor alignment and prevent vibration-induced stress, while the enclosure acts as a protective barrier. It ensures proper heat dissipation through ventilation design, maintains electrical clearance and creepage distances as per standards, and often includes grounding provisions for safety. The design allows for modular expansion and easy access for maintenance while containing potential capacitor failures.

Materials

Galvanized steel (1.5-3mm thickness), powder-coated for corrosion resistance; aluminum alloy for lightweight applications; stainless steel (304/316) for corrosive environments; non-conductive composite materials available for specific insulation requirements.
