The fire-resistant cable will not burn at once under the burning conditions, and can still maintain the normal operation of the line for a period of time. Cables with this characteristic are highly desirable in modern urban and industrial buildings, because once a fire occurs, the power supply loops of the control, monitoring, guidance, and alarm systems can maintain normal operation, so the fire resistant cable is very popular. At present, fire-resistant cables are mainly used in emergency power supply to customer fire-fighting equipment, fire alarm equipment, ventilation and smoke exhaust equipment, guide lights, emergency power outlets, emergency elevators and other power supply circuits. So what problems do workers need to pay attention to when installing fire-resistant cables? 1. When the fire-resistant cable is used in cable-dense cable tunnels, cable interlayers, or in flammable places such as oil pipes and oil depots, Class A fire-resistant cables should be used first. When these conditions are removed and the number of cable configurations is small, a Class B fire resistant cable should be used. Second, fire-resistant cables are mostly used as power supply circuits for emergency power supplies, requiring normal operation during fires. Due to the sharp rise of the ambient temperature during the fire, in order to ensure the transmission capacity of the line and reduce the pressure drop, the cross section of the fire resistant cable should be at least one step for the circuit with a long supply line and strict limits on the allowable voltage drop. Third, fire resistant cables cannot be used as high temperature resistant cables.
A through-bore slip ring is an electrical device that allows current to pass between two points in a rotating assembly without a physical connection. There is no break in the circuit. This is accomplished by passing the current through a rotating brush that contacts a stationary metal ring. The metal ring is mounted on the shaft of the assembly and provides a continuous path for the current.
It is an integrated circuit component that consists of two conducting rings that are separated by a gap or spacer. When the rings are brought into contact, current can flow between them and produce a rotational motion. Slip rings are used in various applications where high efficiency and low power consumption are essential, such as communication systems, motor control systems, and energy harvesting devices.
The through-bore design allows for rotation of the assembly while transmitting power or data. They are often used in applications where there is a need to rotate an object while keeping a power or data connection open, such as on a wind turbine or radar antenna.
The Oubaibo's through-bore slip ring is a newly designed product that has many advantages over other products on the market. It is small and lightweight, making it easy to install and use. The through-bore design also allows for a high degree of flexibility, making it ideal for use in difficult or tight spaces. Additionally, the Oubaibo through-bore slip ring is very efficient, providing a high degree of power transfer with minimal loss.
