Construction of Kangtaier explosion-proof specialized electric heating tape with flame retardant and anti-corrosion electric heating tape

1. Self limiting (automatic temperature control) electric heating strip. As the temperature increases, the resistance of this electric heating strip increases and the power decreases. Due to its high current during startup (instantaneous), the length of use generally does not exceed 100 meters. The electric heating strip can be cut at will. Friendly reminder: The self limiting (automatic temperature control) electric heating strip must not exceed the length of a single 100 meters, and can be cut and used at will. When connected to the rated voltage, it can generate heat.

2. Parallel electric heating strip, where two (or three) parallel insulated copper stranded wires are used as the power bus, and PTC characteristic heating wires are wrapped around the skeleton. The length of each heating section is alternately connected to the bus, forming a continuous parallel resistance. The length of this electric heating strip is about 10-800 meters.

3. Series type electric heating strip, this electric heating strip uses three parallel insulated copper stranded wires with the same cross-sectional area and a certain length as the power bus and heating core wire. One end of them is reliably short circuited, and the other end is connected to a 380V (or designed voltage) power supply to form a star load. According to Joule Lenz's law, Q=0.24IRT electrical energy is converted into thermal energy, and the star load continuously releases heat, forming a continuous and uniform heating electric heating strip. According to actual needs, the three-phase (single-phase) of the electric heating strip can be separated separately (split type) or integrated into one. The length of this electric heating strip should not be too short, usually around 500 to 2500 meters.

4. High temperature electric heating strip, made of fiberglass or other high-temperature resistant materials, can withstand temperatures up to 300 ℃ and has lengths ranging from 1 to 50 meters (as it cannot be cut at will, it needs to be designed by a professional manufacturer).

5. Silicone rubber electric heating strip, which can be used for heating, tracing, and insulation of industrial equipment or laboratory pipes, tanks, tanks, and oil drums (boxes) in damp and non explosive gas places. The length of the electric heating strip is 1-15 meters (as it cannot be cut freely, it needs to be designed by a professional manufacturer)

6. MI cable, this ribbon cable is composed of a metal wire core (heating element), a mineral magnesium oxide (insulation layer) tightly surrounding the wire core, and metal tubes (usually copper, steel, or stainless steel, etc.) that have been drawn multiple times. The continuous working temperature can reach 250-590 ℃, and the short-term working temperature can reach 1083 ℃, resulting in a length of 18-680 meters (as it cannot be cut arbitrarily, it needs to be designed by a professional manufacturer).

The automatic temperature control electric heating belt is equipped with a heat tracing system that automatically adjusts the output power, so it will not burn out due to its own heating. However, it is a new generation of energy-saving type due to the actual need for heat compensation.

*Low temperature state, fast start, uniform temperature, as each part can be automatically adjusted due to temperature changes in the heat traced area. Easy installation, easy maintenance, full day service, high automation level, and low operation and maintenance costs.

*Safe and reliable, widely used, non polluting to the environment, and long service life. The self-control temperature electric heating strip (self regulating electric heating line) is widely used for heat insulation, anti freezing, and anti freezing of pipelines and storage tanks in industrial enterprises such as petroleum, chemical, steel, and power. This cable is suitable for use in general areas, hazardous areas, and corrosive areas. 1.
