Calcium Zinc Compound Stabilizer For PVC Cable Sheath Calcium zinc composite stabilizer for PVC cable sheath is an additive used for PVC cable sheath. It is composed of a mixture of calcium and zinc salts, used to improve the thermal stability and weather resistance of PVC cable sheaths. The addition of calcium zinc composite stabilizers in the manufacturing process of PVC cable sheaths can effectively prevent the decomposition and degradation of PVC materials at high temperatures, and improve the heat resistance performance of cable sheaths. At the same time, it can also enhance the UV and oxidation resistance of PVC cable sheath, extending the service life of the cable. Calcium zinc composite stabilizer for PVC cable sheath is an efficient and environmentally friendly additive that can improve the thermal stability and weather resistance of the cable sheath, and extend the service life of the cable.

The prospect of smart street lights is optimistic about the quiet layout of second and third tier cities
Recently, the reporter learned from the (Guilin) ​​Urban Lighting Management Office that the first phase of Guilin Intelligent Lighting Digital Integrated Management System (hereinafter referred to as the Management System) has completed the surveying and mapping of more than 10,000 street lamps, control base stations and transformers in the city. They are preparing for acceptance and plan to have their own names for these street lights next year. With the construction of the management system, it will not only provide convenience for street lamp management and maintenance, but also the name on the lamp post can provide geographical location for citizens. Smart One: The street light is not bright. I know that this year, the Urban Lighting Management Office and the surveying and mapping unit have carried out the first phase of the intelligent lighting digital integrated management system construction, and the data of the coordinates of the urban 15515 column street light, 350 control base stations and 50 special transformers. The collection, including the type of streetlight, the type of light source, the elevation of the pole, and the illumination of the pole, are all detailed statistics. After the survey is completed, the information will be entered into the intelligent lighting digital integrated management system. This system can realize full-time and all-round management of lighting management objects. When the management system is completed, the situation will change dramatically. These lampposts can automatically alarm when there is a situation where the street light is not lit and the line is disconnected. The person in charge said that the system can show which rod is the faulty street light, where is the fault, and the precise azimuth positioning allows the maintenance personnel to go straight to the scene. In the maintenance, it is not like the street lights that control the base station tube are all turned on before, but the repair is not good, which saves time and avoids wasting electricity. In addition, the street lamp automatic alarm mode can effectively detect and contain the behavior of destroying public lighting facilities. Smart 2: Where did people ask for the streetlight some time ago, a street light pole can be located on the network to locate, must tell the child's information, which said that each street light pole has a string of numbers, this string of numbers is the number of the street light, corresponding The precise location of the location, so when you say the location is not clear when the alarm, it is the easiest way to report the nearby streetlight number. According to reports, there are indeed some cities in the city where the streetlight number is connected with 110 data and realizes the function of streetlight positioning. 110 receives the streetlight number provided by the alarm person, enters the number in the background system, and can display the location immediately. The positioning is not only accurate but also fast. However, such systems are currently only visible in some metropolitan areas such as Shanghai, Shenzhen and Nanjing. In Guangxi, only Nanning has completed and put into use more than 20,000 street lamp coding signs in 2012. Guilin is the second city in Guangxi to build a smart lighting system. The relevant person in charge of the Urban Lighting Management Office told the reporter that to achieve precise positioning of each street lamp, the workload is very large, the location of each street lamp, and the adjacent street lamp. Distances must be accurately calculated. At the same time, road signs such as the first row of buildings, isolation belts, and green belts around the road need to be marked. At present, the relevant departments plan to number the 15,000-plus streetlights, 350 control base stations and 50 special transformers next year, and these names are exclusive to each streetlight. The person in charge said that after the completion of the intelligent integrated digital management system, the named street lamps can cover more than 90 roads (communities) in Xiufeng District, Xiangshan District, Diecai District and Qixing District. The number on the lamppost provides a convenient and fast location service for tourists and citizens. If a tourist gets lost while visiting, or if a citizen needs to call for help, he or she can also provide the number of the street light pole to confirm the location. The person in charge said that in the future, after coordinating with the public security department, the management plan will be coordinated so that the street lights of Guilin can also play the role of precise positioning of the lampposts, so that the intelligent lighting system can maximize the service to the society. What else can be brought apart by intelligence? In addition to being smart, smart streetlights are another feature of energy saving. The relevant person in charge of the Urban Lighting Management Office told the reporter that Guilin began to explore the wisdom of urban lighting in 2001. According to the introduction, at that time, the wireless communication dedicated network was used to realize the real-time monitoring of the operation status of the remote control box of the lighting distribution box distributed in the whole city by the monitoring center. After two upgrades, the intelligent control coverage of the street lamp reached 99. Using Sanyao (telemetry, remote) The letter, remote control system and the new light sensor detection system can select the best switch light time in real time according to the weather conditions of the day, avoiding energy waste caused by premature lighting and turning off the lights too late, achieving energy saving. However, such a control mode is only applicable to the lighting control in the area, and the accuracy is still lacking. After the management system is fully constructed, the intelligent adjustment of the urban lighting system is more flexible, the coverage is wider, and the energy-saving effect will be more obvious. The combination of single lamp control and street lamp intelligent control system can achieve daylighting, daylighting, lighting, and people turning less. At the beginning of this year, Guilin City has completed the single-lamp remote intelligent regulation of 200-inch streetlights between the junction of Qilidian and Dongji Road in the East Second Ring Road, and from the Arctic Plaza to the newly-built intersection, Wushi Street intersection to the North Railway Station. Shanghai Road overpass to Bayi Bridge section, 174 348 ç› street lights are also newly installed with single lamp control information module and optimized control system, according to the changes of road pedestrians and traffic flow, under the premise of ensuring road lighting compliance, reduce the single ç›The brightness of the street lighting can be adjusted by means of one bright one and one side lighting to achieve energy saving and consumption reduction of urban lighting. The person in charge said that after calculation, the power saving rate of single lamp regulation can reach 60. In addition to energy saving, the intelligent management system can realize the real sense of waiting for the alarm, greatly reducing the loss of urban lighting patrol personnel and vehicles.
