Copper Transformer Spades and Copper Transformer Connectors
A1 Metallics is a premier manufacturer and exporter of Copper Transformer Spades, Copper Spade Terminals, and Copper Transformer Connectors. Our copper spades and connectors are precision-engineered components used primarily in transformer manufacturing, power distribution, and high-voltage electrical systems. With over 25 years of expertise in non-ferrous metal fabrication, A1 Metallics delivers products that meet the most demanding performance and quality standards.
Copper transformer spades serve as the critical interface between transformer windings and external busbars or cabling. Their design ensures low contact resistance, high current-carrying capacity, and long-term reliability under thermal cycling and vibration stress.
Product Variants
Copper Spade Terminals
Flat, tab-shaped copper connectors forged or machined to fit onto transformer leads and bushings. Available with single or double holes, various pad sizes, and custom configurations. Also known as: copper lug terminals, copper flat terminals, copper tab connectors, copper tongue terminals.
Copper Transformer Eye Bolts & Spades
Combined spade-eyebolt designs used in oil-immersed and dry-type transformers. Provide both mechanical anchoring and electrical connection. Available tinned or bare copper.
Copper Compression Spade Connectors
Designed for crimping onto conductor ends with a spade terminal for transformer bushing connections. Available in various wire gauge ranges (AWG / mm² formats). Also known as: copper crimped spade connectors, copper crimp terminal lugs, copper spade lugs.
Copper Bus Spades & Flexible Copper Spades
Laminated flexible copper spades for applications requiring vibration absorption and thermal expansion compensation. Common in traction transformers and industrial power systems.
