Description
Technical Field
The utility model relates to the technical field of cables, especially, relate to a novel circular cable of insulating copper core polyvinyl chloride.
Background
Cables are generally rope-like cables made by stranding several wires or groups of wires, each group insulated from the other and often twisted around a center, the entire outer surface being covered with a highly insulating covering. The insulated wire is composed of one or more insulated conducting cores in a sealed sheath. It may be coated with a protective coating for transmitting, distributing electrical energy or transmitting electrical signals. The difference between the cable and the common wire is mainly that the cable is large in size and complex in structure. The existing round cable is easy to leak electricity when in use due to the fact that a protective layer of the cable is easy to damage when in installation and use, and has great potential safety hazard.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving current circular cable and installing and use the time because the protective layer that damages the cable easily leads to the cable to leak electricity easily when using, has very big potential safety hazard to circular cable buries in the underground usually, need bear great pressure, and current cable crushing resistance is not enough to be impaired very easily and is out of shape and lead to shortcomings such as electric leakage, and the novel circular cable of insulating copper core polyvinyl chloride that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel circular cable of insulating copper core polyvinyl chloride, be equipped with the nuclear core portion of a plurality of copper cable cores of group in including and set up in the outside support cover and the protective sheath of nuclear core portion, the outside cover of copper cable core is equipped with insulating cover, the inside of nuclear core portion is provided with a plurality of groups and insulating cover matched with connecting hole, nuclear core portion outer wall parcel has the insulating layer, the outer wall cover of insulating layer is equipped with the support cover.
Preferably, the inner wall of the protective sleeve is provided with a connecting layer, and the outer wall of the protective sleeve is provided with a flame-retardant coating.
Preferably, the insulating sleeve and the insulating layer are both made of polyvinyl chloride.
Preferably, the support sleeve is a double-layer metal braid.
The utility model provides a pair of novel circular cable of insulating copper core polyvinyl chloride, its beneficial effect lies in: the core part 2, the insulating sleeve and the insulating layer are arranged to prevent the copper cable core from electric leakage, so that the insulating property of the cable is improved, and the potential leakage hazard is reduced; the pressure resistance of the cable is improved by arranging the supporting sleeve, and the interference resistance of the cable is improved; the flame-retardant coating is arranged to increase the flame retardance of the cable, so that the cable is prevented from being burnt and damaged; the structure is simple, the practicability is strong, and the popularization is suitable.

Fig. 1 is the utility model provides a novel circular cable of insulating copper core polyvinyl chloride structure sketch map.
In the figure: 1. a copper cable core; 2. a core section; 3. a support sleeve; 4. a protective sleeve; 5. an insulating sleeve; 6. an insulating layer; 7. a connecting layer; 8. and (3) a flame-retardant coating.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a novel circular cable with an insulated copper core and polyvinyl chloride comprises a core part 2, a plurality of groups of copper cable cores 1 are arranged in the core part, and a supporting sleeve 3 and a protective sleeve 4 are arranged outside the core part 2, an insulating sleeve 5 is sleeved outside the copper cable cores 1, a plurality of groups of connecting holes matched with the insulating sleeve 5 are arranged inside the core part 2, an insulating layer 6 is wrapped on the outer wall of the core part 2, the supporting sleeve 3 is sleeved on the outer wall of the insulating layer 6, the core part 2, the insulating sleeve 5 and the insulating layer 6 are arranged to prevent the copper cable cores 1 from leaking electricity, the insulativity of the cable is increased, and the potential leakage hazard is reduced; the pressure resistance of the cable is increased by arranging the supporting sleeve 3, and meanwhile, the interference resistance of the cable is increased.
The inner wall of protective sheath 4 is provided with articulamentum 7, and the outer wall of protective sheath 4 is provided with fire retardant coating 8, increases the fire resistance of cable through setting up fire retardant coating 8, prevents the cable burning damage.
The insulating sleeve 5 and the insulating layer 6 are both made of polyvinyl chloride.
The support sleeve 3 is a double-layer metal braid.
The utility model, when in use, the core part 2, the insulating sleeve 5 and the insulating layer 6 are arranged to avoid the electric leakage of the copper cable core 1, increase the insulativity of the cable and reduce the hidden danger of electric leakage; the pressure resistance of the cable is improved by arranging the support sleeve 3, the anti-interference performance of the cable is improved, the flame retardance of the cable is improved by arranging the flame-retardant coating, and the cable is prevented from being burnt and damaged.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
