Tape Paper Insulation

Description

The construction is simple, and it can be used instead of white gauze tape. The coils are tied and fastened, no need to dip paint, high shrinkage, high tensile strength in hot state, no slack, falling off, and no pollution to transformer oil. It is used for binding (wrapping) the outside of the coil, the head, the transposition and other parts of the coil and the lead wire enclosure in the body during the manufacturing process of transformers, transformers, motors and other electromechanical products.

Advantages of polyester heat shrinkable tape:
Simplify the transformer production process and improve processing efficiency
Minimize woodwork, fasteners and reduce the size of the transformer, greatly reducing manufacturing costs
Significantly improve the product performance and overall quality level of the transformer
High grade, good electrical performance, with an electrical constant of 3, which is better than that between oil and cardboard, and "low stability loss"
Heat shrinkage up to 30%, binding firm, durable, no rebound, no relaxation
, High tensile strength, mechanical strength is more than ten times that of cloth tape.
Pure chemical substance, no burrs, off-lines, markings and other defects on the surface, and does not contain dirt and other substances harmful to electrical insulation
Avoid many corner parts, save cost and save space: more convenient, more reliable, more beautiful
Nominal Width (mm): 20, 25, 30
technical standard:
Broken ends: Each plate is allowed to consist of two sections, each section not less than 5m in length.
