High Voltage SWA Armored Cable
High Voltage SWA Armored Cable, also known as Steel Wire Armored Cable, is a type of Power Cable used for transmitting electrical power at high voltage levels. It is designed to withstand high voltage levels and provide protection against mechanical damage, moisture, and other external factors.

The TV market has always been accompanied by a battle for technological roads. The battle between plasma and liquid crystal has just ended. On the new generation of technology LED TVs, there are two different types of LED backlight technologies, direct-type and side-in, which are in dispute. Since Samsung released a full line of products in China in April this year, various remarks about backlights have sprung up. The main question is the side-in white light.
The evaluation results show that the side-in-white LED technology represented by Samsung has achieved a significant improvement in image quality compared with ordinary LCD TVs, creating a new height in image quality and energy saving. Dr. Wen Na, the National Laboratory of Quality Supervision and Inspection Center of National Radio and TV Products, pointed out that LED TVs have significantly improved performance in terms of energy saving, color, stability and service life compared to CCFL backlight LCD TVs. The indicators are higher than the national technical requirements, especially in terms of contrast and energy consumption.
It is understood that in fact, side-in white light is the latest third-generation LED backlight technology in the industry. After Samsung introduced side-entry products, domestic manufacturers have recently launched a large number of side-entry LED TV products. Although the theory of side-entry does have the problem of "uneven brightness", the third-generation technology "bovine" is that it not only overcomes this problem, but also provides a lower cost and thinner fuselage. 
The cable consists of a copper or aluminum conductor, which carries the electrical current, surrounded by layers of insulation materials such as XLPE (Cross-Linked Polyethylene) or PVC (Polyvinyl Chloride). These insulation layers provide electrical insulation and protect the conductor from external elements.
The SWA (Steel Wire Armored) layer is then applied over the insulation layers. It consists of galvanized steel wires wrapped around the cable, providing mechanical protection and additional strength. The steel wires also help to distribute any mechanical stress or tension evenly along the cable, preventing damage to the conductor.
The armored cable is further protected by an outer sheath, usually made of PVC or LSZH (Low Smoke Zero Halogen), which provides additional protection against moisture, chemicals, and UV radiation.
High Voltage SWA Armored Cable is commonly used in various applications, including power transmission and distribution systems, underground installations, industrial plants, and construction sites. It is suitable for both indoor and outdoor installations, offering reliable and safe power transmission in high voltage environments.
LED backlight technology battle ended
A debate over the 2009 TV market has finally come to an end. With the release of China's first official evaluation results, the side-entry white light technology has set a new benchmark for LCD TV performance with obvious performance advantages, and at the same time, it has made the previous challenges of side-entry type invisible.
