Low-temperature current transformer coil

The invention discloses a low-temperature current transformer coil. The low-temperature current transformer coil mainly comprises a low-temperature glue inner frame (1), a low-temperature insulated wire turn (2) and a low-temperature glue outer frame (3), wherein the low-temperature glue inner frame (1) is arranged in the center of the low-temperature current transformer coil, and adopts a hollow ring-shaped structure; the low-temperature insulated wire turn (2) is formed by uniform winding in the radial direction of the low-temperature glue inner frame (1) of low temperature resistant insulation varnished wire; the head and tail lead wires (23) of the low-temperature insulated wire turn (2) are clung to the outer wall of the low-temperature glue inner frame (1), and are led out from a wire return groove (12) in the outer wall of the low-temperature glue inner frame (1); the low-temperature glue outer frame (3) is ring-shaped, and wraps the low-temperature insulated wire turn (2) and the low-temperature glue inner frame (1) except the lead wires (23).
