Shanghai shangna Electrical Equipment Co., Ltd. was established in November 2018 by Shanghai Songjiang telecommunication equipment Co., Ltd. and Shanghai University. The company is located in Songjiang District, Shanghai, with a registered capital of 20 million yuan. At present, there are 12 scientific research teams of Shanghai University. The company is mainly engaged in the assembly of carbon ceramic resistors, zinc oxide resistors and electrical equipment products assembled by resistors as the core components.
Carbon composite ceramic linear resistance (Sic resistance) is an important component for the safe operation of high voltage power transmission and distribution, high-speed railway and urban rail transit power supply network. It is a new type of linear resistance made of ceramic powder by moulding and firing at high temperature. It has the advantages of small volume, light weight, high energy density and good linearity.
Specific features are as follows:
●Low 100% effective
● High surge energy levels with high pressure resistanceLow
●resistance to high temperature
● Noninductive feature, operating frequency up to megahertz
● Adjustable resistivity range
● Adjustable geometry
● Can work in air, SF6, oil insulation medium environment
● Single plate or modular assembly, flexible shape and assembly
● Resistance is all composed of inorganic materials, pollution-free, long life.
Use
Electric drive, electric traction, current limiting resistance, capacitor charge and discharge resistance, closing resistance, brake resistance, current limiting resistance, grounding resistance, etc.
Metal oxide resistance sheet (MOV), suitable for assembling metal oxide arrester (MOA) of different voltage classes, whether porcelain or silicone rubber coat. Due to its good nonlinear characteristics, excellent absorption capacity of lightning and surge overvoltage energy, MOA is characterized by large overvoltage tolerance, reliable operation, long service life, small size and light weight.
