Beijing, China-January 24, 2013-Silicon Laboratories, a leading manufacturer of high-performance analog and mixed-signal ICs (Core Labs, Inc., NASDAQ: SLAB), will hold the DistribuTECH Smart in San Diego, California, United States from January 29-31 Power Grid Conference showcases wireless solutions for advanced metering infrastructure (AMI). Silicon Labs ’mixed-signal products include wireless radio frequency, ultra-low power 8-bit microcontrollers (MCUs), 32-bit Precision32 ™ MCUs, and digital isolators. They can be used in smart meter communications, sensing, calibration, timing, processing, security, and Reliability and other links are helpful. Silicon Labs will showcase its Ember® ZigBee® SoC and EZRadioPRO® sub-GHz wireless transceivers at the DistribuTECH booth 3433, as well as easy-to-use wireless development tools.
According to a recent market research report from IHS, the current global installation of smart meters is less than 18% of the total 1.4 billion meters installed. It is expected that the installation of smart meters will double by the end of 2016. In addition, IHS predicts that global smart meter shipments will surge in 2015, smart meter projects have already started in Europe and developing economies, and China is the most important market for smart meters.
Silicon Labs is a leading wireless technology provider in AMI applications. Related applications include wireless home area networks (HAN), connecting thermostats and other indoor systems to electricity meters or gateways; and neighborhood area networks (NAN), bringing thousands of thousands The data from each meter is aggregated and passed back to the utility supplier. Silicon Labs' Ember ZigBee products and sub-GHz products provide wireless connectivity solutions for smart meters from AMI's industry-leading manufacturers, including Landis + Gyr, Elster, Itron, Robulink, and Holley Metering.
Diwakar Vishakhadatta, vice president of Silicon Labs and general manager of embedded system products, said: "DistribuTECH provides an opportunity to focus on display, and we will share the expertise of wireless solutions and smart meter applications with important manufacturers in the smart grid field. From silicon chips to Software, we provide smart meter manufacturers with complete solutions to help them reduce the cost and complexity of AMI applications. "

XLPE Insulated Electrical Cable For Rated Voltage 3.6/6KV~26/35KV
For XLPE insulated power cable, either chemical method or physical method is employed to transform the molecular structure of PE from chain into three-dimensional network, i.e. thermoplastic PE is transformed into thermo setting XLPE. After cross-linking, the thermal and mechanical properties of PE have been greatly improved while its excellent electrical property are still retained.
The maximum permissible operating temperature of the conductor of a XLPE insulated power cable is 90℃ which resistance is higher than that of PVC or PE insulated power cable. The cable has the advantage of simplicity in construction, lightness in weight, convenience in application besides its excellent electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with no limitation of level difference along the route.
