Abstract

The utility model discloses an anticorrosion temperature-resistant cable for magnesium thermal resistance. The anticorrosion temperature-resistant cable is characterized in that a conductor is formed by a single silver-coated copper wire or by twisting a plurality of the silver-coated copper wires, a cable core is formed by twisting three conductors covered with insulating layers, and an alkali-free glass fiber wrapping belt layer, a high temperature resistant polyester belt layer, a copper belt shielding layer, a lining layer, a steel wire braided armor and an outer protective sleeve are sequentially arranged on the outside of the cable core in a winding and wrapping manner; four to six silver coated copper lines used as guide lines are longitudinally arranged on the inside of the copper belt shielding layer, and glass yarn ropes are filled between twisted cable cores to form filling layers; and the insulating layers are made of fluorinated ethylene propylene, and the lining layer and the outer protective sleeve are both made of silicon rubber. The anticorrosion temperature-resistant cable is capable of working within temperature range between -60 DEG C and 200 DEG C for long term, has the advantages of high temperature resistance, low temperature resistance, flexibility, corrosion resistance and flame retardance, and is adaptable to needs of power generation work, metallurgical work, petrochemical work and the like under high temperature, corrosive and flame retardant environments.

Description

Magnesium can thermal resistance with anticorrosion heatproof cable

Technical field

The utility model relate to magnesium in the industries such as being applied in generating, metallurgy, petrochemical industry can thermal resistance with anticorrosion heatproof cable.

Background technology

High temperature resistant, anticorrosion cable has demand very widely in high temperature, corrosive environments such as generating, metallurgy, petroleum chemical industry; But the operating temperature range of existing cable is narrower, and it is high temperature resistant, etch-proof effect is not fully up to expectations; Because structure is limit, its useful life is shorter, can't satisfy the needs of generating, metallurgy, the strong rotten operational environment of the contour gentleness of petrochemical industry simultaneously.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of special cable with good high temperature resistant and Corrosion Protection being provided.

The utility model technical solution problem adopts following technical scheme:

The utility model magnesium can thermal resistance with the design feature of anticorrosion heatproof cable be: stranded with sub-thread silver-plated copper lead or multiply silver-plated copper lead is conductor, three stranded formation cable cores of conductor that appearance is coated with insulating barrier, the outside of cable core sets gradually wrapped alkali-free glass fibre belting layer, high temperature resistance polyester belt, copper strips screen, inner covering, braided steel wire armouring and oversheath; , fill with the glass fiber rope between the stranded cable core of each root and form packed layer as drainage thread at the inboard silver-plated copper cash of 4-6 root of vertically placing of described copper strips screen; Described insulating barrier is rare with perfluoroethylene third to be material, and described inner covering and oversheath all are material with silicon rubber.

Compared with the prior art, the utility model beneficial effect is embodied in:

The utility model makes the cable can long-term work in-60 ℃-200 ℃ temperature range, has high temperature resistant, low temperature resistant, soft, corrosion-resistant, fire-retardant advantage, is fit to the needs of high temperature such as generating, metallurgy, petrochemical industry, the fire-retardant environmental work of burn into.

Description of drawings

Fig. 1 is the utility model structural representation.

Number in the figure: 1 conductor, 2 insulating barriers, 3 packed layers, 4 alkali-free glass fibre belting layers, 5 high temperature resistance polyester belts, 6 drainage threads, 7 copper strips screens, 8 inner coverings, braided steel wire armouring 9, oversheath 10.

Embodiment

Referring to Fig. 1, present embodiment be stranded with sub-thread silver-plated copper lead or multiply silver-plated copper lead be conductor 1, three appearances are coated with the conductor 1 stranded formation cable core of insulating barrier 2, set gradually wrapped alkali-free glass fibre belting layer 4, high temperature resistance polyester belt 5, copper strips screen 7 and inner covering 8, braided steel wire armouring 9 and oversheath 10 from inside to outside in the outside of cable core; , fill with the glass fiber rope between the stranded cable core of each root and form packed layer 3 as drainage thread 6 at the inboard silver-plated copper cash of 4-6 root of vertically placing of copper strips screen 7; Insulating barrier 2 is rare with perfluoroethylene third to be material, and inner covering 8 and oversheath 10 all are material with silicon rubber.

Insulating barrier adopts that perfluoroethylene is third rare in the utility model, inner covering and oversheath be material with high quality silicon rubber all, has good mechanical performance, electric property, and has extraordinary flame retardant effect, high temperature resistant, resistance to chemical attack.

The utility model adopts the metallic shield structure also to place drainage thread, but uniform electric field, impedance are little, and shield effectiveness is good, and loss is minimized in the cable, and phase line-zero line impedance loop is little, and overcurrent protection and safety and reliability all increase.

The utility model is filled with the glass fiber rope and the setting of alkali-free glass fibre belting layer, and the selecting for use of insulation, interior outer sheath material, can effectively strengthen the fire resistance of cable.
