Specializes in the manufacturing and processing of electric power fittings,
aluminum parts, and related products.
T-shaped clamp is mainly used for overhead power line or substation, leading down current branch in "t" form on the main line of bus. It is divided into bolt type and compression type,For small cross-section conductor, parallel groove clamp or clamp pressed elliptical connector can also be used as T-type connection.
The meaning of letters and numbers in the product model is as follows:
T-T connection Y-compression L-bolt
The number indicates the nominal cross-sectional area of the applicable conductor.
The grip force of T-clamp on conductor shall not be less than 10% of calculated breaking force of conductor. However, the bolt type clamp is not less than 3% when the conductor diameter is greater than 49mm. Clamp The DC resistance is not greater than the DC resistance of equal length conductor, and the temperature rise of current carrying is lower than that of conductor.
The T-clamp with voltage of 330kV and above shall have no visible corona at 1.05 times of the maximum operating voltage.
