Embodiment Construction

[0023] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below.

[0024] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a core wire 1, an insulating layer 2 is arranged outside the core wire 1, an inner sheath layer 3 is arranged outside the insulating layer 2, a rubber skeleton 4 is installed outside the in...

Abstract

The invention provides a tandem ribbon heater, which comprises core wires, an insulating layer, an inner sheath layer, a rubber framework, reinforcing ribs, a filling layer, a shielding layer, an outer sheath layer, a reinforcing layer and metal wires. According to the tandem ribbon heater, the resistance and the passing current per unit length of the core wires are constant, so that the head andthe tail of the whole ribbon heater are uniform in heating, the output power is constant, and the use length is long. In addition, the tandem ribbon heater is internally provided with the rubber framework, the reinforcing ribs and the metal wires, so that the firmness of a heat tracing band can be better ensured, the core wires inside are not exposed by bending, the safety in use is ensured, and the service life is prolonged.

Description

technical field [0001] The invention relates to an electric heating belt, in particular to a serial electric heating belt. Background technique [0002] Electric heating cables are a new type of high-tech product. Since they entered the application field in the 1970s, they can be widely used in the transportation of liquid objects in pipelines and the antifreeze and heat preservation of tanks, maintaining process temperature, heating roads, and ramps. , Crosswalks, eaves and floors, etc. When the electric heating cable is working, if the heat transferred by the electric heating cable to the system per unit time is equal to the heat transferred from the system to the external environment, the temperature of the system remains unchanged. The highest temperature that the system can reach is called the highest maintenance temperature. [0003] The series electric heating belt is to use three parallel insulated copper strands with the same cross-sectional area and a certain len...
