Electronic tamper-proof smart meter

Smart grids need to protect the security of all components from a physical perspective, which may include smart meters, data concentrators, intelligent electronic devices (IEDs), and security gateways. Freescale offers a high-performance smart meter reference design that integrates an ultra-low power tilt sensor for electronic tamper detection.

The reference design can be connected to a ZigBee® network via an internal daughter card. Therefore, it can easily become an integral part of the smart grid network. The firmware for this reference design is based on the MQXTM real-time operating system. All standard metering values ​​are displayed on the built-in LCD and can be selected via buttons. A variety of communication interfaces are available for remote data acquisition, making it an ideal solution for advanced residential metering.

PVC insulated wires are coated with pvc to prevent from electric shock. Its light weight reduces manual handling difficulties. This wire consists of copper/aluminum conductor, insulated with moisture and heat resistant, chemically cross-linked polyethylene insulation. PVC does not conduct electricity and is therefore an excellent material to use for electrical applications such as insulation sheathing for cables. With fine design and high quality, the wire boasts of large electricity transmission capacity. The maximum continuous operating temperature for general type is 75℃. But the special type BV-105 can work well at the temperature of 105℃.

 

Standard:

GB/T5023-2008, JB/T 8734-2016

 electrical cables with pvc insulator

Rated Voltage:

450/750V

 light weight electrical wires

Application:

cables are extensively used for domestic home appliances wiring, house wiring and internal wiring for lighting circuits in factories, power supply for office automation, in control, instrumentation, submarine, mining, ship wiring applications etc. due to its high tensile strength, superior conductivity, better flexibility and ease of jointing.
