RT-CMC Compact Busway

Product Introduction

RT-CMC Series Low-Impedance Compact Busway uses a typical sandwich structure with closely arranged conductors for overall heat dissipation.The compact design occupies less space,making it a safe and reliable power distribution system.The product's protection level can reach up to IP66 according to user needs.It is suitable for three-phase three-wire,three- phase four-wire,and three-phase five-wire systems(with enclosure as PE,or with PE cross- section half of phase  line),frequency 50-60Hz,rated operating voltage up to 690V,rated insulation voltage up to 1000V,and rated operating current 250-6300A power supply systems. It features stable  reliability,high power distribution efficiency,good heat dissipation,low voltage drop,high  mechanical strength and easy installation.The product can be widely used in large commercial  plazas,buildings,stadiums,hospitals,industrial plants and other projects as an efficient power transmission and distribution system for high currents.The aluminum alloy shell design not only reduces the weight of the busway,but fully considers the high stability requirements of vertical shaft installation,improves system reliability and applicability,and greatly reduces the impact of high-current eddy current and hysteresis loss on the busway system.

Series Power Busbar Number System

Example:RT-CMC 105265-3 indicates:

Model:RT-CMC, current rating:1000A, five-wire system(with independent PE busbar), protection class:IP65, length:3-meter copper busbar straight section.

Products Features

• Intelligent Connector

Single bolt clamping structure,fast and reliable installation;
Double head fixed toraue bolt to ensure the required pressure of connection;
It is equipped with special dish spring to ensure the lasting pressure between thecontact surfaces force;
The clever concave and convex groove design on the edge of the insulation partitionincreases the creepage distance to leave;

• Aluminium Alloy Shell

Busway groove adopts two-piece aluminum alloy profile shell,light weight,machine Hiah mechanical strenath;Effectively avoid eddy current and hysteresis loss caused by the bus slot system Influence;
All aluminum housing has excellent electrical conductivity,the overall housing has 50%to ground capacity on;
The special serrated heat sink greatly improves the heat dissipation of the bus system Force; Special surface treatment,the shell can withstand 2000 hours of salt spray test;
Different from the traditional busway groove shell by two pieces of assembly,the integrity is stronger,higher protection level;the integrity is stronger,higher protection level

• Plug in box

Easy installation and simple operation;it needs an ordinary wrench to finished plug in box,easily insert the mechanica linkage self-ocking mechanism,it the box have not installed,can not be switching on,or power on,it can not open the box,to prevent misoperation,ensure reliable.

• PIN of plug in box

T structure,accurate positioning,universal,stable and reliable.

• Conductor

High speed sawing,smooth incision without burr,high precision sawing,ensure cutting flat,reduces the temperature rise of the busbar joint;
The copper conductor is made of grade A standard copper treated by special process and divided by spectrum  analysis,strict  control of trace element content,conductor copper content ≥99.97%,under the condition of the same section,the loss of the  bus itself is reduced by 3%~5%.Conductor surface processing,unique alloy plating process,lower contact resistance,tin plating,silver plating is optional.

• Polyester

Insulation Heat resistance Class B(130℃);
The voltage can be more than 10000V;
By ROHS standards,no halide,high temperature without toxic gas.

• Intensive jack

The busbar at the socket is not bent,the busbar is full-length intensive;
Low impedance,busduct system has lower voltage drop and line loss;
Fast heat dissipation,large tapping capacity,more safe and reliable tapping current;
Reasonable structure,beautiful appearance,high protection level.

• Unique error-proof device

Unique anti-error phase device,eliminate manual method to identify and confirm the phase sequence,effectively eliminate human factors caused by misinstallation;
