Technical Field
The utility model relates to the technical field of power cable accessories, in particular to an aluminum alloy tail pipe for a high-voltage cable accessory.
Background
The tail pipe for the high-voltage cable accessory needs to be reliably grounded (or indirectly grounded through the sheath protector) during operation so as to normally work. The conventional tail pipe is generally made of copper or copper alloy, and the conductor of the grounding cable is generally a copper core. The conductor of the grounding cable can be connected with the tail pipe through a copper wiring terminal.
Although copper has low electrical conductivity, the tail pipe made of copper is heavy, which is not favorable for convenience of field installation, and also increases the potential safety hazard of the installation process. Therefore, it is considered that the tail pipe is made of an aluminum alloy, and the weight of the tail pipe made of the aluminum alloy is remarkably reduced. However, for the connection of the grounding cable, if the copper terminal of the grounding cable is directly connected to the aluminum alloy grounding lug of the aluminum alloy tail tube, after long-term operation, a large amount of non-conductive aluminum oxide material is generated between the copper terminal and the aluminum alloy grounding lug due to electrochemical action, thereby affecting the grounding effect.
