The relative density of between 1.5 to 2.0, only steel 1/4 to 1/5, but the tensile strength was close to or even more than carbon steel, alloy steel and can be compared with senior strength. Thus, in the aviation, rockets, spacecraft, pressure vessels and the need to reduce the weight of products other applications, all with excellent results. Some epoxy FRP tensile, flexural and compressive strength can reach 400Mpa or more. Good corrosion resistance FRP corrosion-resistant material is good, resistance to air, water and general concentration of acid, alkali, salt and a variety of oils and solvents have better. It has been applied to all aspects of the chemical preservative, and is being replaced by carbon steel, stainless steel, wood, non-ferrous metals. Good electrical properties is an excellent insulation material, used to make insulation. High frequencies can still protect the good dielectric properties. Microwave transmission is good, it has been widely used in radar radome. Good thermal performance FRP low thermal conductivity at room temperature was 1.25 ~ 1.67kJ / (m · h · K), only the metal of 1/100 to 1/1000, is an excellent insulation material. In the case of ultra-high temperature instantaneous Shandong glass steel meter box, it is ideal for thermal protection and ablative material that can withstand high-speed air stream to protect spacecraft at above 2000 ℃ erosion. Cooperation on Environment FRP meter box has any special requirements FRP meter box belongs to a meter box, because of the special nature of the material used and the name. Usually when we use fiberglass meter box installed need to consider the environment to see if it is appropriate. So under what circumstances the meter box to apply it? Measurement FRP meter box smc, and residents metering in life we ??usually installed for outdoor 10KV high for low power meter. Meter box the ambient temperature at + 40-30 ℃ FRP meter box, maximum daily temperature was 25K. + 40 ℃ ambient relative humidity fiberglass meter box, not more than 50%; - 40 ℃ not more than 60%. For inclination also have certain requirements, the cabinet is not up to 3 °; on the meter is not higher than 1 °. FRP meter box when using the maximum wind speed does not exceed 25m / s. Only meet these environmental requirements, glass steel meter box application in order to ensure their safety before they can be assured. FRP meter box, Jinyang Electric, Shandong glass steel meter box provided by LELING Jinyang Electric Co. FRP meter box, Jinyang Electric, Shandong glass steel meter box is LELING Jinyang Electric Co., Ltd.
