BJEPL’s capacitors are manufactured with high-grade metallized polypropylene film. This film is in
the range of microns thick, depending on the application voltage and conditions. The metallized
electrode is several hundred angstroms thick.
The film is wound into a capacitor element on high-speed, high-precision machines. The
winding is
extremely tight so there is not enough space between the layers for corona (localized partial
electrical discharges) to occur. The Elements are sprayed on both ends with metal to make the
connection to the extremely thin edges of the metalized electrodes. This process is critical to the
quality and performance of the capacitors.
The Elements are assembled in appropriate cases, Encapsulation is introduced under vacuum,
and the
capacitors are sealed. They are then subjected to 100% electrical testing for capacitance,
dissipation factor, and high potential electrical withstand, both terminal-to-terminal and
terminal-to-case.
Production Line
BJEPL’s Capacitors are built with biaxially oriented metallized polypropylene film wound into a cylindrical dielectric medium. End contact is formed by zinc metal sprayed on all the layers on each side of the winding, assuring low Effective Series Resistance and low inductance. Metallized polypropylene film provides a self-healing mechanism in which a dielectric breakdown “dissipates” away from the metallization and isolates that area of the capacitor.
Key Competencies & Processes
Innovative manufacturing using Data-Driven Robotic Production Technology
The Passive Electronic components, Capacitors and Energy storage devices being mass-produced require
high precision and standardised repeatability and traceability. We have Innovated, Designed, and
Implemented strategic production systems and technologies into our production line. This
manufacturing innovation takes the pursuit of increased productivity, shortened manufacturing
lead-time, traceability, and improved quality to better limits.
We have Adopted Industry 4.0 Data-Driven approaches across all Supply, Manufacturing,
Operations and
CRM Divisions.
Latest technological adoption and implementations in manufacturing equipment, Robust design,
Selection of raw materials, and Standardized manufacturing process controls added with an Agile
Supply Chain Network contribute to the incrementally improving quality of our manufacturing process
and products.
Real-time Data on all processes can be obtained at each process level.

New Product Development
We Strongly Believe that Technology Invention is driven by needs so we emphasize smart Innovation at every atomic level of our organisation. Technological Leverage combined with managemental Ethics and passion drives our innovation.
Our Design
We Stalwartly believe in designing and delivering a product and its solutions should follow international standards which give it universal acceptance such as IEC, BIS-ISI, CB, JIS, CE, UL, VDE, and global standards. Which enables the end-user to put up our products and solutions for their global operations.
Rapid Prototyping
The selected supply chain allies are equipped with the state-of-the-art technological excellence centers, which complements our design and technical requirements. We use 3D Printing technology for prototyping of External Structures, Mounting Attachments, and Terminal requirements for all our products. This ensures the quality and integrity of the product translated to production. The manufacturing process of capacitors starts by selecting raw materials based on the design and technical requirements. Manufacturing of Capacitors starts with the selection of raw materials based on the design and technical requirements, where most of the raw materials are crafted by our process experts at their Material excellence centers that are reclaimed from our supply network.
