We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for Dry Type Transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry type transformer is 30 years. No crack will form on the surface of transformer winding due to temperature variation as long as the transformer runs under normal service condition.

The new car was developed with the Audi Quattro debuted at the 2010 Paris Motor Show and the Sport Quattro at the Frankfurt Motor Show last year, but the new car incorporates some of Audi's latest technologies, such as laser headlights.
The Sport Quattro Laserlight's laser headlight system consists of more than 50 LED modules with NVIDIA's Tegra 3 processor, which is used with the camera to sense the surrounding environment, in terms of distance and light, and the number and shape of the lighting in different environments. There are differences, regardless of lighting, warnings, pedestrian safety, etc. have a very good performance.
Audi said that the LED lights on the new car are smaller than the traditional LEDs, but the illumination distance is twice that, and the brightness is three times that, and the high beam mode can illuminate up to 500 meters. 
Audi wants to eliminate LED headlight technology will release laser headlights
A few days ago, Audi announced that it will launch a Sport Quattro Laserlight hybrid concept car at the CES International Consumer Electronics Show, which opened on January 8th (January 7th, US time).
