Description

Novel cable with fireproof function

Technical Field

The utility model belongs to the technical field of the cable, specifically indicate a novel cable with fire prevention function.

Background

Cables are generally rope-like cables made by stranding several or groups of conductors, at least two in each group, each group being insulated from each other and often twisted around a center, the entire outer surface being covered with a highly insulating covering. The device is erected in the air or installed underground or underwater for telecommunication or power transmission. The cable may be classified into a power cable, a communication cable, a control cable, and the like according to its use. Compared with an overhead line, the cable has the advantages of small insulating distance between lines, small occupied space, no occupation of space above the ground due to underground laying, no influence of pollution of the surrounding environment, high power transmission reliability, and small interference on personal safety and the surrounding environment. But the cost is high, the construction and the maintenance are troublesome, and the manufacture is complicated. Therefore, the cable is mostly applied to dense areas of population and power grids and places with heavy traffic; when the cable is laid in the river, the river and the seabed, the use of large-span overhead lines can be avoided. The cable can be used in places where the communication interference of the overhead line needs to be avoided and occasions where the attractiveness needs to be considered or the target exposure needs to be avoided, the existing cable is poor in heat dissipation performance and waterproof and fireproof performance, and when a fire disaster occurs, the cable is easily burnt out, so that economic loss is brought to people.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a novel cable that has a fire prevention function that heat dispersion is good, waterproof performance is good.

In order to realize the above functions, the utility model discloses the technical scheme who takes as follows: the utility model provides a novel cable with fire prevention function, includes fire-retardant layer, connecting plate, elastic plate, copper sheath, cable core, insulating layer, fixed band, steel core and filling layer, connecting plate circumference array is located on fire-retardant layer, the elastic plate is connected with the connecting plate, the copper sheath is connected with the elastic plate, the cable core is located the inside of copper sheath, the outside of cable core is located to the insulating layer parcel, fixed band connection insulating layer makes the insulating layer be known as an organic whole, the steel core is located the center department of copper sheath and sets up with the axle center with the copper sheath, the filling layer is full of the gap in the copper sheath.

Furthermore, the elastic plate is provided with a through hole and is made of steel.

Furthermore, the fixing band is made of tensile plastic materials.

Further, the connecting plate is made of copper.

Further, the flame-retardant layer is made of a fire-resistant rubber material.

The utility model adopts the above structure to gain beneficial effect as follows: the utility model provides a pair of novel cable with fire prevention function not only can increase the flexibility of cable through setting up the elastic plate, can also ventilate the heat dissipation to the cable, and heat accessible connecting plate gives off the external world, and the fixed band has increased the steadiness between the cable core, and the copper sheath can protect the cable core to prevent to be burnt out.
