Abstract
The utility model discloses a fully-shielded and grounded metal heating cable, which comprises a heating cable core and a shielding layer. The shielding layer is coated between an inner insulation layer and an outer insulation layer and adopts a metal aluminum strip of 0.6mm multiplied by 15mm, and the end of the shielding layer is connected with a grounding wire. Since the cable core is coated by the metal aluminum strip of 0.6mm multiplied by 15mm to form the shielding layer, and electromagnetic radiation generated in operation of the heating cable can be fully closed by the metal aluminum strip and led into the ground through the tinned copper grounding wire, the impact on and interference to the environmental caused by the electromagnetic radiation of the heating cable can be effectively eliminated, and the strength of the electromagnetic radiation field is far lower than the value specified by the state.
Description
Technical field
The utility model relates to a kind of metal full-shield ground connection heating cable.
Background technology
Heating cable is widely used in the winter heating of folk building such as apartment, villa, hospital, school, hotel, and the Winter protection of outdoor various pipelines, deicing etc., because during its work, the electromagnetic radiation meeting that produces exerts an influence to human body and electric equipment on every side, influences health, disturbs electric equipment normally to move, therefore when making, need shield the heating cable core.Now, what a lot of producers used all is metal mesh shield, and shield effectiveness is poor.
The utility model content
The utility model technical issues that need to address provide a kind of metal full-shield ground connection heating cable of ultralow radiation.
For addressing the above problem, technical solution adopted in the utility model is: a kind of metal full-shield ground connection heating cable, comprise the heating cable cable core and be coated on inner insulating layer and external insulation layer between screen, screen adopts the metal aluminium strip of 0.6mm * 15mm, and the termination of screen connects earth connection.
Described earth connection is the tinned copper wire of 8 0.4mm.
Adopt the beneficial effect that technique scheme produced to be: this novel metal aluminium strip by 0.6mm * 15mm coats cable core and forms screen, the electromagnetic radiation that produces when the metal aluminium strip is worked heating cable is totally-enclosed and import the earth by the tinned copper wire earth connection, solved the influence and the interference of the Electromagnetic Radiation on Environment of heating cable effectively, its electromagnetic radiation electric field strength value is well below the numerical value of national regulation.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As shown in Figure 1, this novel metal full-shield ground connection heating cable comprise heating cable cable core 4, inner insulating layer 3, external insulation layer 1 and be coated on inner insulating layer and external insulation layer between screen 2, its screen adopts the metal aluminium strip of 0.6mm * 15mm to twine parcel and forms, the cable core that will generate heat shields fully, the termination of this metal aluminium strip screen connects earth connection, earth connection adopts the tinned copper wire of 8 0.4mm, the electromagnetic radiation that produces when earth connection is used for cable worked imports the earth, the influence and the interference that have solved the Electromagnetic Radiation on Environment of heating cable effectively.
After heating cable adopts metal full-shield grounding technology, the electromagnetic radiation electric field strength value during heating cable work: 0.08V/m, electromagnetic intensity value: below the 0.05uT.Electromagnetic radiation electric field strength value with national regulation: 4000V m, the electromagnetic intensity value: 100uT compares, well below the value of national regulation.
Claims (2)
