Thiết bị đầu cuối bảo hiểm:
As for its insulating material, we will also use modified nylon (PA66) at this time, which will have better electrical and mechanical properties. The screw is made of high-strength copper alloy, the conductor is made of electrolytic copper, and the wire frame is made of alloy copper that is resistant to stress crack corrosion. These metal surfaces are also tin-plated or directly nickel-plated for protection.
The all-copper bar terminal can effectively avoid the battery effect of steel metal parts and copper wires in a humid environment. There is a connecting hole in the middle of the terminal. In this regard, it means that it can not only be connected to the center, but also can be connected by an edge plug connector; in actual use, it can also be connected to a 4mm2 wire with a voltage of 800V. 41A electrical products.
Test terminal:
The sliding metal parts that function as switches can also withstand a large working current through the terminal crimping frame. When switching, a screwdriver will be used to loosen the screws. At this time, we also need to move the slider. It is clear at a glance; there are test sockets at both ends, and the corresponding test terminals can be used for connection testing, and the operation can be uninterrupted when measuring current. It can be connected to a control loop with a voltage of 660V and a current of 57A.
