The connection of the overhead transmission line wires and the ground wires adopts a large number of crimping type electric power fittings, strain clamps and linear splicing sleeves, which are not only required to bear the whole tension of the wires and the ground wires, but also are conductors, and are not dismounted after being mounted. In the construction process, the lead and the ground wire do not penetrate into place in the crimping pipe or the steel core is in crimping failure, so that the major hidden trouble is buried for the safe operation of the line. In the national range, the fault of broken wire and broken wire caused by unqualified crimping quality of the strain clamp or the splicing sleeve occurs too much. Therefore, nondestructive testing of strain clamps and splicing sleeves has begun to be popularized nationally.

The technology utilizes the strong penetrating power of X-rays, the rays penetrating through the measured object carry information reflecting the internal structure of the measured object, and the property, the size and the distribution condition of various macroscopic or microscopic defects in materials or workpieces are detected and judged through the change of the intensity of the rays.
Aiming at the three-span line of the ultra-high voltage transmission line, the three-span line is put forward as the central importance of the operation and maintenance of a main power grid, and in order to prevent the occurrence of larger public safety and power grid safety incidents caused by hidden danger of the three-span strain clamp, nondestructive flaw detection is required to be adopted for the three-span strain clamp of the ultra-high voltage transmission line.
