<p>A safety televiewing method for CATV is provided, wherein part of sheath layer in the shielding layer of the CATV cable is stripped off, and stripping at the connection joint to the ground wire with a ground resistor of 0.5~2 omega to obtain the cable core of 8~10cm length, scraping off the oxidation layer, connecting and winding at the place entering room, and wrapping mechanically or by tin soldering for insulation. The present invention has a simple process, and has good protection effect for CATV televiewing.</p> |
