Keywords: wire and cable selection First, the general principle of wire and cable selection In the selection of wire and cable, generally pay attention to wire and cable models, specifications (conductor section) choice. 1. Selection of wire and cable models When using wire and cable, consider the use, laying conditions and safety; for example, depending on the application, choose the power cable, overhead insulated cable, control cable, etc.; depending on the laying conditions, use general plastic insulated cables, steel strips Armored cable, wire armored cable, anti-corrosion cable, etc.; according to safety requirements, non-flammable cable, flame retardant cable, halogen-free flame-retardant cable, fire-resistant cable, etc. can be used. 2. Selection of wire and cable specifications When determining the usage specifications (conductor cross-section) of wire and cable, the selection conditions such as heat generation, voltage loss, economic current density, and mechanical strength should generally be considered. According to experience, the low voltage power line has a large load current, so generally select the cross section first according to the heat conditions, and then check its voltage loss and mechanical strength; low voltage lighting line can first press the allowable voltage loss condition because of its higher voltage level requirements. Select the section, and then check the heating conditions and mechanical strength; for high-voltage lines, first select the section according to the economic current density, and then check its heating conditions and allowable voltage loss; and high-voltage overhead lines, but also check the mechanical strength. If the user has no experience, they should consult the relevant professional unit or person.

The long beaked teapots we saw for the performance are mostly bronze, and some are made of iron and tin, also known as the long spouted teapots. A tea maker with no flow is called a no flow pot, which can also be slightly raised; Short flow kettle --- a teapot with the spout water outlet separated from the chamber within three inches; Medium flow kettle --- the distance from the water outlet to the kettle chamber is about three inches to two feet; The teapot whose spout is more than two feet away from the pot cavity is called a long flow pot. In ancient times, the spout of Changliu Pot was usually three feet long, which is why the commonly known "one meter long pot" came into being.
