Embodiment 1

[0036] combine figure 1 with figure 2, is a high temperature resistant cable disclosed by the present invention, including a core 1, a protective layer 2 and a high temperature resistant layer 3 are arranged on the outer side of the core 1, the protective layer 2 is placed on the side close to the core 1, and the protective layer 2 The card slot 4 is formed by indenting toward the direction close to the wire core 1, and the position where the high temperature resistant layer 3 is facing the card slot 4 protrudes toward the direction of the card slot 4 and forms a card bar 5 that is plugged and adapted to the card slot 4, and the card slot 4 and The mutual cooperation of the clip strips 5 strengthens the connection between the protective layer 2 and the high temperature resistant layer 3, so as to achieve the effect of improving the stability of the cable during use.

[0037] refer to figure 2 The protective layer 2 includes an insulating varnish layer 21, a rubber particle...

Embodiment 2

[0043] A production process for high temperature resistant cables, comprising the following steps:

[0044] S1, apply the insulating varnish evenly on the surface of the wire core 1, and smoothen the outer surface of the insulating varnish applied on the surface of the wire core 1;

[0045] S2, glue the rubber particle coagulation layer 22, glass fiber layer 23, polytetrafluoroethylene layer 24 and quartz layer 25 together layer by layer from inside to outside, and make the rubber particle coagulation layer 22 and glass fiber layer 23 at one end extend outward Form the overlapping layer 7, so that the polytetrafluoroethylene layer 24 and the quartz layer 25 at the other end extend outward to form the connecting layer 8;

[0046] S3, bonding the heat-conducting silicone grease layer 31, the heat-conducting silica gel layer 32, the refractory clay layer 33 and the ceramic fiber layer 34 together layer by layer from inside to outside;

[0047] S4, set the rubber particle coagula...

Abstract

The invention relates to a high-temperature-resistant cable and its production process, which belongs to the technical field of cable manufacturing. On the side, the protective layer includes an insulating varnish layer, a rubber particle condensation layer, a glass fiber layer, a polytetrafluoroethylene layer and a quartz layer that are arranged in sequence away from the wire core; the high temperature resistant layer includes thermally conductive silicone grease that is arranged in sequence in a direction away from the quartz layer Layer, heat-conducting silica gel layer, refractory clay layer and ceramic fiber layer; the protective layer is recessed toward the direction close to the wire core to form a card slot, and the position where the high temperature resistant layer is facing the card slot protrudes toward the direction of the card slot and forms a slot suitable for insertion into the card slot. The matching clip strip, the present invention has the effect of improving the stability of the use of the cable.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a high temperature resistant cable and a production process thereof. Background technique [0002] Cable is a general term for items such as optical cables and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. High temperature resistant cables are an important development direction of modern safe electric power transmission technology, and some industries have higher and higher requirements for high temperature resistant performance of wires and cables. [0003] The existing Chinese patent whose notification number is CN207925152U can be referred to, which discloses a high temperature resistant cable, including a wire core, the outer wall of the wire core is coated with an insulating varnish layer, and the outer wa...
