Problems solved by technology

[0002] In the current power equipment construction, before power transmission or when the cables have been laid after construction, it is necessary to fireproof the panel box. However, due to the omission of cable design and the addition of new power signals, new cables must be laid To the panel box, it is necessary to destroy the original plugging, lay cables, and then restore the plugging, which not only destroys the original equipment, but also has low laying efficiency

Abstract

The present invention relates to the fields of method and devices special for installation, maintenance, repairing or dismounting of cables or wires, concretely to a cable reel box with a preformed hole and an application method thereof. The cable reel box with the preformed hole comprises a reel box (1), and a casing pipe (4), the casing pipe (4) sleeves the position between the bottom portion ofthe reel box (1) and a fire partition layer (2), the outer end of the casing pipe (4) is arranged at the outer portion of the fire partition layer (2), and the inner end of the casing pipe (4) is arranged in the reel box (1). According to the cable reel box with the preformed hole and the application method thereof, the use method is implemented as follows: seal; and cable punching. The protection device is convenient to lay, low in cost and high in construction efficiency.

Description

technical field [0001] The invention relates to the field of methods or equipment specially used for installing, maintaining, repairing or dismantling cables or wires, in particular to a cable reel box with reserved holes and a use method thereof. Background technique [0002] In the current construction of electric power equipment, before power transmission or when the cable has been laid after the construction, it is necessary to fireproof the panel box. However, due to the omission of the cable design and the addition of a new power signal, it is necessary to lay a new cable To the panel box, this has to destroy the original plugging, lay cables, and then restore the plugging, which not only destroys the original equipment, but also has low laying efficiency. Contents of the invention [0003] In order to overcome the defects of the prior art and provide a cable installation method with protection equipment, convenient laying, low cost and high construction efficiency, ...
