Low-voltage electrical appliances generally have two basic parts: one is the sensing part, which senses the external signal and makes a regular reaction. In the self-controlled electrical appliance, the sensing part is mostly composed of an electromagnetic mechanism, in the controlled electrical appliance, the sense The measuring part is usually an operating handle or the like; the other is an executing part, such as a contact that is turned on or off according to an instruction.
Equipment introduction
According to the working voltage of low-voltage electrical control equipment, it is divided into two categories: high-voltage control appliances and low-voltage control appliances according to the AC 1200V and DC 1500V.
A low-voltage electrical appliance is a component or device that can manually or automatically turn the circuit on or off according to external signals and requirements to switch, control, protect, detect, change and adjust the circuit or non-electrical object.
In general, low-voltage electrical appliances can be divided into two major categories of distribution electrical appliances and control electrical appliances, and are the basic components of complete electrical equipment. In the industrial, agricultural, transportation, defense, and people's electricity sectors, most use low-voltage power supply, so the quality of electrical components will directly affect the reliability of low-voltage power supply systems.
The development of low-voltage electrical appliances depends on the development of the national economy and the needs of the development of modern industrial automation, as well as the research and application of new technologies, new processes, and new materials. Currently, it is moving toward high performance, high reliability, miniaturization, and digital modeling. The development of modularization, combination and component generalization.
KS Standard Glass Beads,Appearance: colorless transparent sphere, round and smooth, no obvious bubbles or impurities.1,micro glass beads for road marking paint as reflective material; 2, glass beads for road marking paint; 3 glass beads for traffic. 4; round rate of ≥ 80%; Density :2.4-2 .6g/cm3; refractive index: Nd ≥ 1.50 .
REFLECTIVE GLASS BEADS – drop on / premix beads
For the visibility of road markings reflective glass beads are a major component. Together with the marking material the reflective glass beads constitute the retroreflecting system. The micro glass beads embedded in the marking material reflect the headlight of the car, hence the marking lights up at night. This [lighting up" – retroreflection – makes the road marking better visible for the driver and is thus an important and crucial factor for road safety.
Reflective glass beads as drop on or premix beads:
increase road safety through better visibility at night as well as in particularly bad weather conditions, like fog or rain. improve the life span and the durability of the road marking due to their hardness are a particularly economical factor for traffic guidance and road safety
blyglassbeads one of China reflective glass beads factory can offer a wide range of products and reflective glass beads with refractive indices ranging from ≥ 1.5 to 1.9. In addition it is guaranteed that impurities (e.g. iron) are minimized and/or heavy metal contents.
The production of all reflective glass beads confirms to national and international standards (BS6088, EN 1423, EN 1424, AASHTO, etc.).
Individual customer requests are possible with any type of reflective glass beads.
