Transformer Bushings: Provide insulation between the transformer and external conductors, ensuring safe power transfer.
Transmission Lines: Support and insulate overhead conductors on transmission towers. The insulators’ mechanical strength and insulation properties maintain line integrity over long distances and in harsh weather (e.g., strong winds, ice loads).
Substations: Play a role in internal wiring and equipment connections, contributing to the overall stability of the substation’s electrical system.

Insulation and Durability: While our glass insulators offer consistent creepage distances and mechanical strength across models, competitors may have variations. Some competitors’ products might have less uniform creepage distance, increasing the risk of partial discharges over time. In terms of material durability, our insulators’ glass composition, especially with RTV coating in certain models (like U160BP), provides better resistance to environmental aging compared to some competitors’ non - coated or differently formulated products.
Customization and Flexibility: We support customization, including OEM/ODM, allowing adaptation to unique project requirements (e.g., specific spacing, coupling needs). Some competitors have more rigid product lines, making it harder for customers with specialized needs to find a perfect fit. For example, if a project requires a non - standard coupling design, our ability to modify products gives us an edge over competitors with limited customization options.
NJREC has built a good reputation for high quality products, timely delivery and responsive customer service. And has kept its development process, considering his responsibilities and missions about being one of the esteemed and respectful companies in the transformer bushing, transmission line and substation industry.

Ordering and Payment: We accept T/T (30% deposit, 70% balance against B/L copy) and 100% irrevocable LC at sight. Competitors may have different payment terms; some might require full payment upfront, which can be a cash - flow burden for customers. Our 24 - hour inquiry response by sales teams is also a competitive advantage. Some competitors have longer response times, delaying project planning and execution.
Certification and Quality Assurance: With ISO9001 certification and test reports, we ensure quality. Competitors may have varying levels of certification; some might lack comprehensive quality - management system certifications, raising concerns about product consistency and reliability.
