The flat type busbar is a reliable and space-efficient power distribution system designed primarily for overhead cranes, electric hoists, and other mobile equipment requiring continuous power along a travel path. Known for its slim profile and easy installation, the flat busbar system is ideal for environments where low headroom and tight spaces are a concern.
Unlike enclosed-type busbars, flat-type busbars are typically open or semi-enclosed and consist of flat, rigid copper or aluminium conductors mounted in an insulating carrier or track. Current is transmitted to moving equipment via sliding collector shoes that maintain contact with the live conductors as the crane or trolley moves.
Key Features:
- Compact & Low-Profile Design: Ideal for applications with limited installation space or low headroom requirements.
- Durable Conductors: Available in copper or aluminum, sized to handle various current ratings (typically 60A to 400A or more).
- Insulated Support Track: Holds and separates conductors while preventing short circuits and enhancing operator safety.
- Continuous Power Supply: Provides uninterrupted electrical contact for moving equipment through collector trolleys or shoes.
- Modular & Extendable: Easy to cut, join, and extend according to runway length and layout.
- Simple Maintenance: Open access to conductors allows for straightforward inspection and replacement of parts.
- Optional Covers & Accessories: UV-resistant covers, end caps, joint covers, and hanger clamps available for added protection and customization.
Technical Specifications (Typical):
- Current Ratings: 60A to 400A (custom systems may support higher)
