Busbar Heat Shrink Tube Heating Tunnel Oven

The Busbar Heat Shrink Tube Heating Tunnel Oven is a continuous, high-efficiency automated heating and forming equipment specially designed for the heat shrinkable insulation sleeves applied to copper or aluminum busbars in high and low voltage electrical cabinets and substations.The equipment uses a conveyor system to transport busbars fitted with heat shrink tubes at a constant speed into a closed heating tunnel. Through far-infrared radiation heating or hot air circulation, the heat shrink tube is uniformly heated and tightly shrunk around the surface of the busbar, achieving reliable insulation protection.

Applications

High and Low Voltage Switchgear Industry

Used for long-distance insulation covering of copper and aluminum busbars with various specifications inside distribution cabinets and switch cabinets.

New Energy Vehicle Industry

Used for insulation heating of battery pack (PACK) internal cell connection busbars and electric drive busbars.

Rail Transit and Transformer Industry

Used for protection of busbars in locomotive traction power supply systems and large-scale transformer outlet copper bars.

Standards

The design and production of the equipment generally need to strictly comply with the following industrial standards:

GB/T 10067.1 / GB/T 10067.4 Basic technical requirements for electric heating equipment in China, including general requirements and indirect resistance furnace specifications.

GB 5226.1 / IEC 60204-1 Safety of machinery — Electrical equipment of machines — General technical requirements.

CE Certification

For export applications, the equipment should comply with European safety and electromagnetic compatibility requirements.

Features

360° Uniform Heating Performance

Uses multi-directional far-infrared thermal radiation or specially designed mesh conveyor processes to completely solve problems caused by traditional manual heat gun heating, such as surface bubbles, pressure marks, and uneven heating.

Precise Temperature Control and Variable Speed Regulation

Adopts a high-precision PID intelligent temperature control system with temperature accuracy within ≤ ±1°C. The conveyor speed can be continuously adjusted to perfectly match heat shrink tubes of different thicknesses.

High Efficiency, Energy Saving, and Safety

The middle layer of the oven chamber is filled with thick high-temperature insulation cotton (temperature resistance up to 1200°C), effectively reducing heat loss, lowering external surface temperature, protecting operators from burns, and significantly reducing energy consumption compared with conventional ovens.
