The insulation and groove clamp is used for the connection of the small and medium-sized section of the aluminum strand or steel core aluminum strand and the steel strand of the overhead lightning conductor in the position of not bearing tension, and also for the jumper connection of the non-linear tower. Power engineering materials (fittings) connecting wires are mainly used in power line engineering.
The insulated and groove line clamp comprises an upper cover assembly, a lower cover assembly, a connecting assembly and a plurality of grippers.
Product Description:
According to China's standard GB2314 "General Technical Requirements for Power Accessories" and the power industry standard DL/T 765.1 "Technical Conditions for Overhead distribution line accessories", the grip force of non-load-bearing parallel groove fixture on the wire should not be less than 10% of the breaking force of the wire tension calculated, and the conductivity should not be lower than the resistance of the contact wire.
At the same time, in order to ensure stability and reliability, the resistance change index after the current through the clear requirements. Meeting these requirements can ensure the normal operation of the line, or when overload or even short circuit occurs, the parallel groove fixture does not fail before wiring, to ensure the safety and reliability of the line.
Characteristics:
The current conduction between conductors can be analyzed from two aspects: the mechanical contact area of conductors and the current conduction path.
Mechanical contact area of a conductor:
From the microscopic point of view, the surface of a conductor is composed of numerous uneven peaks and valleys. The smoother the conductor surface, the smaller the difference in height between the peaks and valleys.
When two conductors contact under external force, the contact is mainly in the form of peak to peak contact. Therefore, the actual mechanical contact area is far less than the nominal contact area of fixture design, the actual mechanical contact area is about 7% of the nominal contact area.
