An ultra-high voltage direct current (DS) power cable may be provided via a conductor formed by twisting a plurality of strands, an inner semiconducting layer surrounding the conductor, an insulating layer surrounding the inner semiconducting layer; and an outer semiconducting layer surrounding the insulating layer, wherein the insulating layer is formed of an insulation composition containing a polyolefin resin and a crosslinking agent, and the insulating layer is divided into three equal parts in a thickness direction, the three equal parts including an inner layer, an intermediate layer and an outer layer.

Ultra-high voltage direct current power cable

Provided is a power cable, and particularly, to an ultra-high-voltage power cable of 45 kV to 600 kV. Specifically, the present invention relates to a power cable which is eco-friendly and includes an insulating layer formed of an insulating material having not only high heat resistance and mechanical strength but also high flexibility, bendability, impact resistance, cold resistance, installability, workability, etc., which are in trade-off with heat resistance and mechanical strength, and of which the lifespan, flexibility and installability can be additionally improved through precise control of a thickness of the insulating layer according to characteristics of the insulating material, thereby enhancing workability.

A mobile TV receiver is provided in which the viewing screen can move left and right or up and down and be tipped or tilted by remote control as the viewer chooses. The TV receiver is divided into a head portion including a CRT-tube and a lower body portion accommodating driving elements and supporting the head portion. The head portion is adjustably connected to the upper part of the supporting body portion so that only the head can lean over, tilt up and down, and move upward and downward by operation of the driving elements under the viewer's control. The viewer can thus remote-control the TV set back and forth, and adjust it exactly as desired to make the TV screen comfortably visible.
