BL Series

A Flexible, Safe, and Reliable Low Voltage Power Distribution Solution

The Busway BL Series from Delta are made from epoxy using vacuum casting. Superior to traditional cables or sandwich type busway solutions, Delta’s Busways significantly improve the protection ratings, safety and reliability of products, are ideal for use in harsh environmental conditions, and can be extensively applied to a range of industries. Thanks to the outstanding electrical and mechanical properties of resin, these busways have reduced dimensions, a simplified structure, extended service life, and improved reusability. More importantly, Delta’s Busways provide excellent energy-savings to help our customers enjoy substantial savings on their electricity bills.

Innovative Energy-saving Materials

     
Normal busways have high power-consuming resistors in conductors, leading to expensive electricity bills. Delta’s Busway uses state-of-the-art technology to not only cut electricity costs, but also effectively reduce electromagnetic interference, preventing damage to precision equipment.
  • CoAlly Technology
    Conductors are set to the optimum low-resistance state to reduce energy consumption as well as carbon footprints, while contributing to environmental protection and low power costs.
  • SiShield Technology
    With a low-impedance electrolytic copper plate, the conductor has optimum low resistance, effectively reducing loss and voltage drops. In addition, the internally coated composite significantly mitigates electromagnetic interference to protect precision equipment.
 

Flexible and Cost-saving

     
  • Delta’s Cast Resin Busway system is only 60% of the size of traditional sandwich busways, and 30% of the size of traditional electrical cable wiring.
  • The busway joint is constructed as moving connecting modules, easy to assemble, disassemble, expand, and reuse when changing layout.
  • The plug-in unit works with MCCB from major manufacturers allowing live line operations at anytime to change loads without cutting off power and saving both time and money.
  • Maintenance-free throughout its service life, reducing OPEX.
Applications
With the rapid growth of global IT industry, factories are built to increasingly large scales. This adds to the demand for quality power supply, safe power transfer and efficient systems, as well as greater expandability. As busway development has reached higher levels of reliability, safety and flexibility due to fast delivery and flexible engineering changes, busways are now used extensively in a variety of industries.

In addition to power transmission/distribution, Delta’s Busways also feature high protection ratings and are ideal for harsh environmental conditions and mission critical applications required high reliability and safety.
