What is the basic principle of the copper tube lug?

1. The alphanumeric blockchain system consists of large Latin letters and Arabic numerals. 2. On the first part of the character, from A to M, select the letters that mark the DC component, and on the second part of the letter, from N to Z, select the letters that mark the AC part. The letters "I" and "O" cannot be used, but the characters "+" and "-" can be used. 3. If the copper tube lug symbols are not confused, some parts of the complete alphanumeric symbols are allowed to remain.

What is the identification principle of the copper tube lug?

The identification of the wiring copper tube lugs follows the following principles: 1. Divide a two-part wiring copper tube lug into two consecutive numbers, the odd number should be less than the equal number, such as 1 and 2. 2. The central copper tube lug of a part is divided by a number. The difference is that it is much better to use the numbers in a more natural order. Examples: 3, 4, 5, etc. The number of copper tube lugs in the middle should be greater than the numbers on both sides, and the marking starts from the copper tube lug with the smallest number. For example, the central copper tube lugs with terminals 1 and 2 on both sides are marked with numbers 3, 4, 5, etc. 3. When several similar components are combined, the terminals of each component can be linked to the following system symbols: a. The numbers mentioned in 5.2.1 and 5.2.2 are prefixed with letters to separate the copper tube lugs on both sides and the terminals in the middle. For example, U, V, W are used to mark the copper tube lugs of each of the three mechanical categories. Phase AC system. If it is not necessary or impossible to identify a part, enter the numbers specified in 5.2.1 and 5.2.2 to separate the terminals on both sides from the middle copper tube lug. To avoid confusion, please add a dot between these numbers. For example, the terminals of one component are marked as 1.1 and 1.2, and the copper tube lugs of another component are marked as 2.1 and 2.2; C. The two-copper tube lugs of each element are marked with different consecutive numbers. To divide, the odd number of the fraction must be less than the equal number.
