1, the nature of different: copper terminals are for copper cable crimping terminals, the whole is pure copper, copper and aluminum terminals are for aluminum cable crimping terminals, crimping tube part is aluminum, screw eye part is copper.
2, different specifications: the concept of copper terminals is broader, copper terminals have plug type, fence type, spring type and so on. And copper nose is a unified form of specifications.
3, the role of different ranges: copper terminals are used to realize the electrical connection of an accessory product. Copper nose is used for wire and cable connected to the electrical equipment on the connector, the top side for the fixing of screws on the side, the end of the stripped wire and cable on the copper core.

Precautions:
1, construction personnel in the use of terminals do not meet the national standards of spare parts to be resisted, refused to use, the use of materials to put a good pass. Secondly, the material department should be a good way to purchase goods off, the organization of the procurement staff should be more grass-roots visits to understand the use of the purchased items in the installation process, and timely collection of the use of opinions.
2, the reasonable distribution of electricity load, the establishment of a regular load measurement system: because the distribution lines sometimes extend several kilometers, or even dozens of kilometers, to consider the power of the user's power equipment, capacity, pay attention to the field, the development of power programs should be ahead of the time, the reasonable distribution of the three-phase load, not only to consider the economy of electricity and to achieve the security of electricity.
3, must take more effective lightning protection measures to ensure safe and stable operation of the cable. For the cable leads to the distribution line to carry out regular inspections, the distribution line on both sides of the trees should be regularly repaired, the facilities affecting the safety of the line to clear the amount of rectification, to ensure that the line perimeter is free of obstacles to reduce the periphery of the distribution line failure factors and natural hazards.
