What is a Network Cabinet? The network cabinet is a kind of rectangular cabinet composed of two parts: frame and cover, which can install switches, optical fiber adapters, optical fiber distribution frames and other equipment in a cabinet, with electromagnetic isolation, noise isolation, ventilation and heat dissipation, anti-vibration, anti-corrosion, etc.

1. Power failure: The power supply of the fan fails, such as the power cord is disconnected, the power plug is loose, etc., which will cause the current to fail to transmit normally, resulting in the fan stopping and rotating. 2. The temperature is too low: Some heat dissipation windbreakers have a temperature protection function, when the temperature is too low, the fan will automatically ...

1. External force damage. Judging from the operation analysis in recent years, especially in Haipudong, which is developing rapidly, a considerable number of cable failures are caused by mechanical damage. For example, the cable laying and installation is not standardized, which is easy to cause mechanical damage; Engage in direct burial on cables ...

Industrial wires and cables include single-core wires and cables, rubber cables, shielded control cables, flame-retardant cables, fire-resistant cables, etc. Single-core wire and cable It means that there is only one conductor in the insulation layer, the common BV wire, and B represents the wiring; V stands for insulating polyvinyl chloride. Suitable for AC ...
