Ningbo Haoguang Electric Appliance Co., Ltd. wire production project has been completed.
5G, the fifth-generation communication technology, has a theoretical peak transmission speed of 1GB per 8 seconds, which is more than 10 times faster than the transmission speed of 4G networks.
Advantages of copper wire in making safer and effective cables
A:There are five basic types of Fire Alarm Cable:
FPL - Power Limited General Purpose
FPLR - Power Limited Suitable from Floor to Floor
FPLP - Power Limited Suitable for use in Ducts, Plenums, and other spaces
NPLF - Non-Power Limited General Purpose
NPLFP - Non-Power Limited Suitable for use in Ducts, Plenums, and other spaces
A:In the United States, smaller conductors are measured using the American Wire Gauge (AWG). With the gauge system, the higher the number is, the smaller the cable will be. For larger wires, circular mils are used. MCM sizes, also called kcmils (kilo-circular mils), are for even larger cables. One MCM is equivalent to one thousand circular mils.
A:UL stands for “Underwriter‘s Laboratory” and is an independent US testing organisation, similar to the German VDE. Based on the the National Electrical Code (NEC, also referred to as NFPA 79) – the safety standard prevalent in the USA for electrical installations – the Underwriter’s Laboratory defines standards for electrical components and their fields of application. UL approvals are also recognised as safety standards in many other countries due to the strict fire protection requirements found in the NEC.
