Abstract

The utility model discloses a flat cable for drilling, which includes a cable core. The cable core includes three sets of grounding conductor wire cores, four sets of control conductors and two X-shaped skeletons. The two X-shaped skeletons are arranged side by side to The cable core is divided into multiple cavities, the three groups of grounding conductor cores are respectively arranged in the left, middle and right three cavities, the four groups of control conductors are arranged in the remaining four cavities, and the grounding conductor wires The core is made of two strands of aluminum alloy conductors arranged in parallel and tangentially and bundled into bundles by adhesive tape. The control conductor is formed by twisting multiple strands of pure nickel wire bundles. The utility model is equipped with a self-locking armored moisture barrier Between the self-locking armored moisture barrier and the outer sheath, there is a fiber tape tensile wrapping layer coated with semi-conductive colloid, a mixture filling layer of talcum powder and magnesium carbonate, so that the cable has good moisture resistance Tensile performance enables it to work underground for a long time, prolongs the service life of the cable and saves costs.

Description

A flat cable for drilling

technical field

The utility model mainly relates to the field of cable design and processing, in particular to a flat cable for drilling.

Background technique

At present, my country's power industry has developed rapidly, especially the transformation and development of urban power grids. The demand for power cables will increase day by day. At the same time, cables are required to have higher strength, flexibility and some new capabilities. However, the current power cables are still There are shortcomings such as insufficient insulation effect, poor tensile capacity, and short service life, which need to be improved.

Utility model content

The purpose of the utility model is to provide a flat cable for drilling in order to remedy the defects of the prior art.

The utility model is achieved through the following technical solutions:

A flat cable for drilling, including a cable core, the cable core includes three sets of grounding conductor cores, four sets of control conductors and two X-shaped skeletons, the two X-shaped skeletons are arranged side by side to divide the cable core into multiple three cavities, the three groups of grounding conductor cores are respectively arranged in the left, middle and right three cavities, and the four groups of control conductors are arranged in the remaining four cavities, and the grounding conductor cores are composed of two strands The aluminum alloy conductors are arranged in parallel and tangent to each other and bundled into bundles by adhesive tape. The control conductor is twisted by multiple strands of pure nickel wire, and the outermost sides of the two X-shaped skeletons are wrapped with self-locking armored moisture barrier layer, fiber tape coated with semi-conductive colloid, a composite filling layer of talcum powder and magnesium carbonate, and an outer sheath, the outer sheath is a chlorosulfonated polyethylene sheath.

The utility model has the advantages of:

The utility model is equipped with a self-locking armored moisture barrier on the outside of the wire core, and is provided with a fiber tape coated with semi-conductive colloid and a stretch-resistant wrapping layer and talc powder between the self-locking armored moisture barrier and the outer sheath. The mixture filling layer with magnesium carbonate makes the cable have good moisture-proof and tensile properties, so that it can run underground for a long time, prolong the service life of the cable, and save costs.

Detailed ways

As shown in Figure 1, a flat cable for drilling includes a cable core, and the cable core includes three sets of grounding conductor cores 1, four sets of control conductors 2 and two X-shaped skeletons 3, the two X-shaped The skeletons 3 are arranged side by side to divide the cable core into multiple cavities. The three groups of grounding conductor cores 1 are respectively arranged in the left, middle and right three cavities, and the four groups of control conductors 2 are arranged in the remaining four cavities. Among them, the grounding conductor core 1 is made of two strands of aluminum alloy conductors 4 arranged in parallel and tangentially and bundled by adhesive tape 5, and the control conductor 2 is formed by twisting a plurality of strands of pure nickel wire. The outermost side of the X-shaped frame 3 is also sequentially wrapped with a self-locking armored moisture barrier 6, a fiber tape tensile wrapping layer coated with semi-conductive colloid, a mixture filling layer 8 of talcum powder and magnesium carbonate, and an outer sheath 9 , the outer sheath is a chlorosulfonated polyethylene sheath.
