The product enclosure has IP23 degree of protection. It is protected against rain, snow, ice, and foreign objects. The product undergoes a rigorous assessment of various test environments and insulation properties. Operation and maintenance personnel touch the outside of the power transmission conduit without any danger.
reliable:
The collector of the product walks in the conduit, and the copper guide rail is embedded in the conduit. Therefore, the relative position of the collector's walking track and the copper guide rail is constant. The current collector brush and the copper guide rail are always in constant pressure contact to ensure the reliability of the contact. . Brushes are made of a cermet material with high electrical conductivity and high wear resistance. The current collector moves flexibly, has good directional performance, and can effectively control the contact arc and the arc phenomenon.
economic:
The structure of the product is simple. Due to the electrical conductivity of copper-based steel, the node is 15% compared with bare copper wire, and material and installation costs are greatly saved.
Convenience:
The DHG and DHGJ devices incorporate multi-pole busbars in one conduit, which is easy to install. The fixed brackets, connections, and suspension devices are provided in standard parts. It is very convenient to install, disassemble, adjust, and maintain.
A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
