Test methods and requirements for crimping and mechanical connection fittings for power cable conductors with a rated voltage of 35 kV (Um=40.5 kV) and below. Scope 1: This standard is applicable to crimping and mechanical connection fittings for power cable conductors with a rated voltage of 35 kV (Um=-40.5 kV) and below, such as for directly buried cables or cables installed in buildings. These cables are conductors that comply with the GB/T 3956-2008 standard, with a copper core conductor cross-sectional area of over 10 mm2 and an aluminum core conductor cross-sectional area of over 16 mm2. b) The maximum continuous operating temperature of the conductor shall not exceed 90 ℃. This standard does not apply to connection fittings on overhead conductors, which have special mechanical requirements and require special design. This standard also does not apply to detachable connection fittings or multi-core connection fittings with sliding connections (i.e. slip ring connection fittings). Although it is not possible to accurately determine the usage conditions for all applications, connection fittings can still be divided into two categories: Class A: Class A connection fittings are suitable for distribution or industrial networks that can withstand relatively long and high short-circuit currents. Therefore, Class A connection fittings can be used in most environments Class B: Class B connection fittings are suitable for networks equipped with protective devices (such as fast fuse devices) that can quickly eliminate overload or short circuit circuits. According to the different applications of the connecting hardware, the following tests shall be conducted on the connecting hardware: - Class A: thermal cycling and short circuit tests—— Class B: Only conduct thermal cycling tests. The purpose of this standard is to determine the methods and requirements for type testing of crimping or mechanical connection fittings for copper or aluminum conductors of power cables
Function of testing report:
