How does the control cable terminal head calculate?
Do not know not to say that the wrong control of the cable terminal head according to the core number
1. A cable requires two cable terminations 2. The cable terminations are accessories that protect the end of the cable. The general power cable needs to be the end of the terminal. The terminal is usually connected to the switch or power equipment of the switchboard 3. A loop may consist of multiple lines
Determination of cable end. 1) Determination of high-voltage cable terminal A cable using two sets of cable terminal, if the cable ends are used in the room, the use of two sets of indoor cable terminal, if one end is outdoor, one end is indoor Inside and outside the set, if both ends are outdoor, then use two sets of outdoor. In addition, in special environments such as humidity, serious pollution and other places, regardless of indoor and outdoor use outdoor cable terminal. B According to the equipment to determine, according to the switch device into the line through the two calculation cable terminal, if the end of the line for the outdoor overhead connection, the overhead connection using outdoor cable terminal. If the transformer is the cable into the line, according to the number of incoming and outgoing times by 2 to get the number of terminals. 2) low-voltage cable terminal to determine the general is also based on a cable 2 sets of terminals to confirm that the current foreign low-voltage terminal indoors and outdoors, if the special requirements are stated when ordering. But sometimes do not know the number of cables only know the equipment drawings, it is based on the number of incoming and outgoing lines to confirm, a line into a set, a outlet calculation of 2 sets, usually taking into account the entry and exit are a piece of time in accordance with the entry and exit The number of cable terminals can be multiplied by 2. Special attention, the general 6 square below the cable can be calculated without the number of terminals and direct connection.
A cable regardless of the number of cable, according to two terminal head, according to a large cross-section to take.
