Product features of explosion-proof electric heating cable manufacturers

Information source: Anhui Cable Group Co., Ltd. Browse times: 36 Release time: 2020-01-16

Electric heating cables can be widely used for liquid objects in pipelines and antifreeze insulation of tanks, maintaining process temperature, heating highways, ramps, crosswalks, eaves and floors, etc., can be divided into low voltage types (12-36V) according to voltage ), Medium voltage type (100-660V), high voltage type (380-650V). Because industrial applications require products with explosion-proof characteristics, many customers will ask how the products of explosion-proof electrical heating cables have explosion-proof characteristics.

Installation drawing of explosion-proof electric heating cable
Here we introduce to you, electric heating cable manufacturers will produce electric heating cables according to customer requirements. If customers need electric heating cables to have explosion-proof characteristics, manufacturers will add a layer of metal shielding network to the cable. This layer of shielding network has explosion-proof characteristics. If anticorrosive performance is needed, add a layer of fluorine material outer sheath. The explosion-proof electric heating cable can effectively prevent and resist static electricity and mechanical collision. Customers may have doubts here whether explosion-proof and anticorrosive electric heating cables can be used in explosion-proof occasions. Of course, it is possible, but explosion-proof electric heating cables cannot adapt to corrosive environments, because it does not have anti-corrosive performance.
As long as the user purchases the explosion-proof electric heating cable from the manufacturer, the product quality is basically no problem, and most of the problems are caused by the installation. Below are some installation error methods that are prone to failure at the end:
1. The tail end is a sealed section. During the installation process, a tail junction box needs to be installed for sealing. It is strictly forbidden to leak the tail of the electrical heating cable without installing the junction box. When the tail end is wet, it is easy to cause a short circuit.
2. When installing the terminal box, the outer sheath should be peeled off and the shielding layer should be peeled off. It is strictly forbidden to connect the electric heating shield to the terminal box. If the shielding network is connected to the terminal box, the circuit will be grounded. In a state of poor contact, electric sparks are easily generated.
3. The use of water-absorbent insulating tape causes the tail end to be wet and cause failure.
4. The tail end insulation expands and contracts thermally, exposing the conductive part, which causes failure in wet conditions such as rain and snow.
