The pole can be easily folded and stored when not in use, making it an ideal solution for temporary lighting applications. It can also be used in areas where traditional poles are not feasible due to space constraints or other limitations. The folding pole is easy to install and can be quickly set up by a single person. It can be adjusted to different heights and angles, allowing for customized lighting solutions that meet the specific needs of any project. Overall, the folding pole for streetlights is a versatile and practical solution that offers a range of benefits to urban planners, lighting designers, and maintenance crews. hinged pole,hinged light pole,mid hinged light pole,mid hinged pole,hinged cctv pole Yangzhou M.T.

What is the difference between flameproof type and intrinsically safe type Zeng'an type?
Intrinsic safety is designed in accordance with the GB3836.1-2000 standard, specifically for use in coal mine environments where explosive atmospheres may exist. This standard outlines the classification of explosion-proof electrical equipment, which includes three main types: flameproof, increased safety, and intrinsically safe. Intrinsically safe equipment is unique because all its circuits are designed to be inherently safe. Under normal operation or during specified fault conditions, any electrical sparks or thermal effects produced by the device are insufficient to ignite a flammable gas mixture. This means that the device does not rely on a protective enclosure or filling material to prevent explosions. Instead, the energy level of any spark or heat generated is kept below 0.28 mJ, which is lower than the minimum ignition energy of a gas mixture at its most explosive concentration—typically around 8.5% methane.
Flameproof (or "d" type) equipment, on the other hand, is constructed with a robust enclosure that can contain an internal explosion without allowing it to ignite the surrounding atmosphere. The design ensures that any sparks, arcs, or hot surfaces that could potentially ignite an explosive gas mixture are fully enclosed within the housing. If an explosion occurs inside the enclosure, the structure is strong enough to withstand the pressure and prevent the spread of flames or hot gases to the external environment. Additionally, the presence of gaps or joints in the enclosure allows for cooling of the flame, reducing its temperature and slowing down the propagation of the flame, thus preventing ignition of the surrounding explosive atmosphere.
The flameproof type is further divided into different categories based on the type of explosive gas atmosphere it is suitable for. These include Group I (for mines), Group IIA, IIB, and IIC, each corresponding to specific flammable gas mixtures. Flameproof equipment is commonly used in Zone 1 and Zone 2 hazardous areas, where the risk of explosive gas accumulation is present but not constant. This makes it ideal for applications in industrial and mining environments where safety is a top priority.
