Features & Advantages

Large Phase Spacing Design

The RTZM medium-current lighting busway adopts a large phase spacing design to support the insulation capacity of the system. This structure helps maintain safe phase clearance and stable electrical performance in low-voltage power distribution applications.

Simple Structure for Easy Maintenance

The system is designed with a simple and practical structure, making it easier to install, maintain and adjust on site. This is especially useful for project environments where the busway layout, tap-off points or installation conditions may need to be adapted during implementation.

Single Arm Bolt Locking Design

The busway adopts a single arm bolt locking design, helping improve installation efficiency and connection stability between busway units. This design supports faster assembly while maintaining reliable mechanical connection.

Non-Reversible Connection Design

The unique non-reversible design helps prevent incorrect connection between busbar units during installation. This reduces the risk of installation errors and supports safer system assembly.

Expansion Gap Between Units

A unit connection expansion gap is designed between busway sections to help reduce the effect of linear expansion. This supports the electrical conductivity and mechanical strength of the overall busway system.

Aluminum Alloy Profile Housing

The aluminum alloy profile housing is compact, lightweight and easy to install. It provides sufficient strength to support and protect the bus duct system, helps avoid mechanical damage and supports good electrical continuity.

The non-magnetic housing material helps avoid eddy current effects, while the aluminum alloy structure supports heat dissipation and helps reduce temperature rise during operation. The housing also provides corrosion resistance for long-term use in suitable indoor environments.

Insulation Materials and Creepage Distance

The insulation materials inside the busway are selected to support heat resistance, insulation performance, mechanical strength and anti-aging ability. The safety distance and creepage distance between internal phases are designed to support stable electrical performance.

Monitoring Options for Data Center Applications

For data center end power distribution, the busway can be configured with temperature monitoring and full electrical parameter monitoring systems according to customer requirements. Plug-in units and feeder boxes can support RS485 bus solutions and Modbus protocol for integration with power and environmental monitoring systems.

Basic Electrical Characteristics

The RTZM Medium-Current Lighting Busway 63-400A is available in multiple rated current options for low-voltage power distribution projects. The following electrical characteristics help engineers evaluate resistance, reactance, impedance, voltage loss, rated voltage, insulation performance and withstand capacity during product selection.

General Electrical Parameters

Unit Functions

Straight Length

The straight length is the main power distribution section of the RTZM medium-current lighting busway system. It supports standard and customized lengths to match different project layouts.

Plug-in Unit

The plug-in unit is used to tap power from the busway system and supply connected loads. It supports flexible component configuration according to project requirements.

For data center applications, tap-off boxes can be equipped with comprehensive electrical parameter monitoring modules, supporting RS485 bus solutions and Modbus protocol for integration with power and environmental monitoring systems.

Flange End Box

The flange end box is used for cable transition from the power supply end to the busway system. It can be configured according to current rating, component requirements and project installation conditions.

When used in data center scenarios, the feeder box can be equipped with a comprehensive electrical parameter monitoring module, supporting RS485 bus solutions and Modbus protocol for integration with power and environmental monitoring systems.

Direction-Change Units

Direction-change units help adapt the busway layout to actual site conditions. Only part of the elbow range is displayed; configurations can be flexibly adapted to specific on-site requirements.

Accessories & Installation

The RTZM medium-current lighting busway system should be installed according to approved installation drawings, selected busway sections, connectors and related accessories.

During installation, the confirmed short busway section should be positioned on the pre-mounted support brackets. The connector bolts are loosened first, and the connector is then attached to the busway.

The next busway section is installed on the pre-mounted support brackets on the other side of the connector. During alignment, the N-phase should follow the same-side principle. After the busway alignment is adjusted, the connector bolts are tightened with a wrench.

After the connector is secured, the upper and lower joint cover plates are installed and fastened with bolts. This installation structure supports project-based assembly and helps simplify future maintenance or layout adjustment.
