High Quality Transformer Spades, Transformer Spade Terminals, Bronze Transformer Spade Connectors, Bronze Spades, Bronze Spade Terminals for Transformers
We are one of the leading manufacturers and exporters of Transformer Spades and Bronze Transformer Spade Terminals from India. We have been supplying these components to the world market for many decades. Our products are engineered for high-conductivity applications and are widely trusted by transformer manufacturers, electrical contractors, and utility companies across the globe. Each spade terminal is manufactured to ensure mechanical strength, corrosion resistance, and dimensional stability under high thermal and electrical loads. Whether for dry-type, oil-filled, or distribution transformers, our Bronze Transformer Spade Connectors are designed to meet stringent international standards. We offer NEMA spaced transformer connectors and transformer Spade terminals and Bushings for pole mounted transformers.
We offer a complete portfolio of standard as well as custom-made spades and terminals in Copper and Bronze alloys, with flexible production volumes and turnaround times. Our in-house tooling and CNC machining capabilities allow us to manufacture with precision and consistency, catering to both small batch requirements and large-volume contracts. We also provide customized packaging options with customer logo and labeling as required.
Transformer Spades : Transformer Spades are flat, perforated metallic connectors used to establish reliable electrical connections in transformer bushing terminals. Manufactured using high-conductivity Bronze or Copper alloys, these spades are designed to endure harsh operational environments. Typical applications include high-current bus bar interfaces and transformer winding terminations. Spades are punched with precision-machined holes for bolt fastening and come in rectangular, round, or custom profiles.
Transformer Spade Terminals : Transformer Spade Terminals are terminal-end fittings shaped like a flat blade or fork, used in securing electrical conductors to transformer terminals. These parts are fabricated using stamping and CNC machining processes from Bronze or Copper sheets and are surface-finished to improve conductivity and oxidation resistance. They are essential components in ensuring low-resistance electrical paths in transformers.
Bronze Transformer Spade Connectors : These connectors are specifically made using high-strength Bronze alloys (like CuSn5, CuSn6, or CuZn33) which offer a blend of excellent conductivity and mechanical durability. Bronze Transformer Spade Connectors are typically used in medium- and high-voltage applications where thermal fatigue and corrosion can be critical concerns. They are often electro-tinned or silver-plated as per application demands.
Bronze Spades: Bronze Spades are manufactured using CDA 510, IS 318 LTB2, or BS 1400 LG2 grades of Bronze. These are fabricated via stamping, pressing, and CNC machining, followed by surface finishing processes. Bronze Spades ensure strong mechanical performance and are suitable for rugged field installations.
Bronze Spade Terminals for Transformers : These are the final connection elements mounted on transformer bushing studs or terminals to connect conductors. We offer these terminals in multiple hole configurations and plating options (Tin, Nickel, Silver). They can be supplied with flanged or threaded stems depending on the bus bar interface or transformer flange design.
