Power cables, which act as the mainmeans of providing objects with electricity, are laid by a trench method. In this case, there is a high probability of accidental damage to the lines. To protect the cables from unwanted mechanical influences, today a special slab is used.
Plates for closing electrical conductorshave become widespread everywhere relatively recently. Such funds have replaced the other practical method of protecting the cable in the form of a cover with construction bricks.
Plate PZK is designed for insulation of electricalpower lines that operate under voltage from 0.4 to 35 kW. Among other things, such a convenient mobile device is suitable for coating pipelines of small diameter, gas network elements, the operation of which requires protection from all sorts of damages.
Modern PZK plates for cable protectiondiffer a special variety of colors. However, the defining parameter of the individual embodiments is the width parameter, despite the fact that the length of all products is identical and is 48 cm. The PLZ plate can correspond to the standard sizes: 48 x 24, 48 x 36, 48 x 48.
What are the advantages of the slab of the PZK cable when laying power cables in the ground? Attention deserves the following:
Separately, it is worth paying attention to the highindicators of strength of cable closure plates, extreme resistance to mechanical influences of the most diverse properties. These qualities favorably isolate such isolation against the background of the same ceramic brick, which in the past was universally used to protect power lines laid in the ground.
