BPTM: Providing Exceptional Busbar Insulation and Protection

Busbars play a critical role in electrical power distribution systems, transmitting power efficiently and reliably. However, to ensure their safe and efficient operation, busbars require insulation and protection against various environmental factors. That's where TE Connectivity's (TE) Raychem BPTM (Busbar Insulation Tubing) comes into the picture. BPTM is a medium-wall, heat shrink tubing designed to provide exceptional insulation enhancement and protection for busbars.

One of the key features of BPTM is its exceptional insulation capabilities, even at high continuous operating temperatures. This makes it suitable for use in both indoor and outdoor applications. Whether exposed to extreme heat or freezing cold, BPTM maintains its insulation integrity, ensuring long-term reliability.

In addition to its insulation properties, BPTM offers several other advantages. It exhibits excellent anti-tracking properties, meaning it resists the formation of conductive paths on the surface due to tracking or erosion. This feature is crucial in preventing flashovers and accidentally induced discharges that can lead to equipment failure or even electrical fires.

Moreover, BPTM is flame retardant and halogen-free, making it a safe choice for applications where fire safety is a concern. In the event of a fire, the halogen-free polymer used in BPTM significantly reduces the release of noxious and corrosive gases, minimizing the potential harm to people and equipment.

Another notable characteristic of BPTM is its good thermal emissivity. This property allows the tubing to dissipate heat efficiently, preventing excessive temperature buildup and ensuring the busbars operate within their optimal temperature range.

TE Connectivity's BPTM tubing is designed for ease of installation. It can be applied to both circular and rectangular copper or aluminum busbars. When heated, the tubing shrinks snugly over the busbar profile, achieving the required minimum wall thickness. It can be easily installed using an oven during large-scale production or in the field using a gas torch or hot air.

By using BPTM, equipment designers gain flexibility in reducing air spacing between busbars, particularly in applications where space is limited, such as switchgear cabinets. The tubing provides reliable flashover protection up to 25 kV, ensuring safe operation even in high-voltage environments.

TE Connectivity takes pride in delivering consistent, high-quality products backed by their proven innovation and exceptional customer support. BPTM is compliant with REACH and RoHS regulations and has received UL approval, further validating its performance and safety.

To assess the suitability of BPTM for specific applications, TE provides key product specifications and ordering information. These include thermal endurance, accelerated aging, tensile strength, elongation, tracking resistance, dielectric strength, volume resistivity, low-temperature flexibility, smoke index, acid gas generation, and flammability.

The BPTM tubing is available for both round and rectangular busbars, with various sizes to accommodate different voltage classes and dimensions. TE provides a comprehensive selection guide, making it easier for users to choose the appropriate tubing for their specific busbar requirements.

TE Connectivity's BPTM tubing not only ensures reliable insulation and protection for busbars but also contributes to space optimization, fire safety, and long-term performance. With its exceptional properties and ease of installation, BPTM is a trusted solution for a wide range of electrical power distribution applications.
