New energy cable manufacturer When the two ends of the cable shared with you are connected with other electrical equipment, a connection device that can meet certain insulation and sealing requirements is required. This device is called a cable terminal. The cable terminal head can be divided into indoor head and outdoor head according to the different use occasions. The device that connects several cables to form a longer cable line is called the middle head. The indoor head, outdoor head and middle head of the above cable are collectively referred to as three heads of cable.
Basic requirements for three ends of cable: the conductor shall be well connected; Reliable insulation; Good sealing; Sufficient mechanical strength.
power cable divide:
(1) According to the production and installation materials: heat shrinkable (the most commonly used), dry wrapped, epoxy resin casting and cold shrinkable;
(2) According to the core material, it can be divided into: copper core power cable connector; Aluminum core power cable connector;
(3) According to the joint material, it can be divided into plastic cable head and metal cable head.
Function of cable head
Make the line unobstructed, keep the cable sealed, and ensure the bonding at the cable joints, so that it can operate safely and reliably.
Main problem: the cause of the joint heating:
When laying wires, installation workers often do not pay attention to installation quality; For example, no sleeve is installed at the place where the insulating pipe should be used; Where junction boxes should be used, junction boxes should be installed. The hot wire connector will not only cause a lot of power loss, but also seriously affect the normal operation of electrical equipment, ranging from the increase of working current in the line, the shortening of electrical equipment life, or the sudden interruption of electrical equipment, resulting in losses, even fire and electric shock accidents.
