The behavior of the LDRB isolators is highly linear in shear stiffness and the damping ratio is 2 - 3% of critical damping. There is no creep in the material and the stability of the modulus of elasticity is very good. Advantages of LRDB insulators; they can be modulated in a simpleway and they are less affected by the factors that have mechanical behaviors. These insulators may need additional damping elements.

Low voltage combination switch Mining explosion-proof and Intrinsically Safe Low-voltage Vacuum Combination Switch (hereinafter referred to as combination switch) is used in coal mines containing explosive gas and coal dust. It can logically control and protect the start-up or stop of 4 sets of three- phase squirrel-cage asynchronous motors under rated voltage 1140V (660V), AC 50Hz, and can change the phase sequence when the motor stops. The switch is especially applied to centralize monitoring of mining, transportation and other kinds of working faces with centralized dynamic loads. The switch has advantages like high automation level, convenient and intuitive man-machine dialogue, easy to networking, stable performance, sensitive protect, reliable operations, etc. It is a perfect upgrade product for mine digitization. Wantai founded in 1998, now the net worth is 430 million yuan, focused on the research and development, production and sales of the Mining Explosion-Proof Equipment , High Voltage Combination Switchgear, and Miner' s Lamp is also our main underground products.
Mining Explosion-proof Vacuum Feeder Switch Mining Vacuum Feeder Switch equipped with high-performance PLC Vacuum Feeder Switch that dedicate to serve the feeder switch to protect and monitor. The product has various protection functions such as overload, short-circuit, leakage interlock, leakage protection, under voltage, over voltage, three-phase imbalance, gas interlock, interlocked circuit breaker, selective leakage protection, three-phase balanced protection, long distance short-circuit protection, communication networking. Our Intrinsically Safe Vacuum Feeder Switch is also available. Square switch with quick-actuating closures structure. The whole structure is small and nice. The switch is equipped with quick plug-in connection and the technology is simple and direct Powerful function of communication network Standard RS485 interfaces are equipped with the device. Seamless joint field device can be realized. That makes it convenient to establish site monitoring system. The product has 4T (telemeter, telecommunication, telecontrol and teleregulation) functions and it is easy to access substations underground and merge into industrial Ethernet. Concentrated monitoring in ground control center now is available.
Our Optically Isolated RS232 card convert TTL logic of the UART (controller ) to RS 232 (PC)via .Optical isolators.This isolator provides very reliable communication in noisy area sometimes running of counts happens when a weighing scale board is connected to pc via simple MAX232 chip .
