  The hotline is a high temperature, heating up fast, long life, stable resistance, low-power bias, even after stretching pitch, the surface bright and clean, widely used in large and small industrial furnaces, heating and air conditioning equipment, various types of ovens, heating pipes and household electrical appliances. According to user needs, design and production of various non-standard industrial and civilian grate. The hotline is a voltage limiting protection devices. Utilizing nonlinear characteristics of the varistor, when over-voltage occurs between the two poles of the varistor, the varistor voltage can be clamped to a relatively fixed voltage value, in order to achieve protection of the post-stage circuit. The main parameters of varistors are: varistor voltage, current capacity, the junction capacitance and response time.
 
  Hotline ns response time level, discharge faster than air, slightly slower than the TVS tube, generally over-voltage protection for electronic circuits to meet the requirements of its response speed. When the junction capacitance of the varistor is generally on the order of hundreds to thousands of Pf range, and in many cases should not be applied directly to the protection of high-frequency signal lines, the application in the AC circuit protection, as it will increase the drain junction capacitance larger current protection circuit design need to be fully considered. Varistor flow capacity is larger, but smaller than the gas discharge tube.
 
  The hotline is added on top of it when the voltage falls below its threshold "UN", the current flowing through it is very small, the equivalent of a shut valve, when the voltage exceeds the UN, the surge current flowing through it, equivalent to the valve opens. Using this feature, you can suppress the circuit often appear abnormal over-voltage, over-voltage protection circuit from damage. In addition to the hotline play a protective role, "safety valve", it will also bring some additional impact, which is called "secondary effects", which should reduce the normal performance of the system. Then the main factors to consider, there are three, one varistor itself capacitance (tens to tens of thousands PF), the second is in the system voltage, leakage current, three are non-linear current source impedance through the varistor coupling effects on other circuits.
 
  It introduced a large number of various electric wire, resistance band, offers a number of products and services for various industries, electric cable Ltd. Dongguan tasked with many of the world's leading professional manufacturers have a close working relationship. Meanwhile, the company to take advantage of Internet, not only to provide the most extensive selection of products for users to get the best character than, users can also quickly provide scientific and technical information.
 
  First, the advantages of the electric board
 
  1, electric panels, mostly thin flat plate design, simple structure heat evenly, easy to install and use.
 
  2, electric panels made of stainless steel, ceramics and other materials as the outer casing, electric heating alloy wire is enclosed inside the heating plate, and therefore is a closed heating, heat no fire, no smell, good safety, applicable to all kind of working environment.
 
  Second, many of the advantages of the use of electric plates, it is a very popular application in the production of life, from the ordinary to the heating, electric thermos to keep the ambient temperature laboratory experiments, and ultimately, the use of electric panels. Currently, electric panels have been widely used in various fields of industry, agriculture, civil, defense, science and technology and health care and so on.
 
  Third, the classification of electric panels currently no clear classification in the market, Cable Co., Ltd., Dongguan Driven electric hot plate, stainless steel electric panels, ceramic heating plate, silicone rubber heating plate, carbon crystal electric panels and carbon fiber heating panels, the main difference is in the different outer shell material or inner heat different materials, such as stainless steel and ceramic heating plate heating plate belongs to a different shell material, the remaining heat in several different materials.
 
  Fourth, the principle of electric hot plate heating material for heating alloy wire, it works is very simple, it is a basic electric effects. When electric panels work, the electric current through the wire, electric alloy wire will heat, electrical energy is converted into heat, and transfer to the outer shell. Electric panels designed with insulation materials to ensure the current user does not work when heating alloy wire safety hazard.
