When it comes to crystal heads, we usually think of accessories for connecting network cables. Although in hydropower construction, household weak electricity also needs to be transformed, but usually the crystal head does not need to be specially connected by the master. Nowadays, the installation of network sockets has become the mainstream, and the crystal head will only be used in the later use of network equipment. However, when one of the owners was renovating the water and electricity, the master provided a pack of crystal heads and charged an additional 50 yuan.
Initially, the owner felt a little repulsed by the master's approach, believing that such treatment was unnecessary. However, after the completion, after hearing the master's explanation, the owner felt that it was worth it and praised the master electrician for being very professional. The master explained that this crystal head is not used to modify the network cable, but to connect the switch socket line. Of course, the owner can choose not to use it, but the master prefers the owner to use it. His purpose is not to make an extra 50 dollars, but to ensure that the owner is safer when using electricity and reduces potential risks.
The owner agreed to this extra charge after hearing the master's explanation. After all, hydropower safety cannot be overlooked. While the master was working on the thread end, the owner did notice the difference. Unlike other masters who directly wrap two wires together and wrap insulating tape, the master directly connects the wires to the crystal head, that is, uses the crystal head as a bridge to connect the two wires together. Not only is this easier to operate, but it also avoids the problem of short circuits in the joints, which can easily lead to short circuits or excessive wire loads that can cause burning problems.
The master explained that in fact, the additional charge of 50 yuan was mainly the cost of materials. This thing that looks like a crystal head is not a crystal head, but a wire connector. It is indeed safer to connect wires with it. Even in the case of excessive wire loads, the connector does not burn and only melts slowly. Therefore, it is safer than traditional wiring.
In my opinion, I personally also recommend using this connector to handle the line when retrofitting hydropower. This is possible not only when connecting wires, but also when parallel wires. Moreover, this connection method can also solve the problem that the switch and socket panel is difficult to install due to the large number of lines in the cassette. Since the cost is also very limited, it is a good method to learn from.
