Temperature sensing wire for electric wires

This product is a "danger temperature alarm" that connects a temperature sensing wire to a small alarm panel to monitor and alert for dangerous temperatures (80°C). It features a structure where a shape memory alloy is combined at equal intervals along an extended wire; when the surrounding temperature reaches the set temperature (80°C), the two wires short-circuit to sense the temperature and send a signal. It adopts eco-friendly technology with zero standby power, making it easy for anyone to install. Despite its simplicity, it offers good accuracy and can be used for both indoor and outdoor wiring, allowing for wiring similar to that of electrical equipment. This product meets the performance standards of type 1 fixed temperature detectors (120 seconds) as specified by fire safety regulations, making it ideal for use in places at risk of dangerous (abnormal) temperatures, such as buildings under construction, plant factories, thermal power generation, various conveyors, and chemical industry piping. ■ Contact information regarding this matter 2-2-8 Minami Tsutsujigaoka, Kameoka City, Kyoto Prefecture 621-0847 Space Works Contact: Wada wadakame@siren.ocn.ne.jp TEL: 0771-25-3430 / FAX: 0771-25-4932

■Overview of Temperature Detection Sensor for Distribution Boards 1. This is a product with a temperature detection sensor (80℃) connected by a cable. It is connected using crimp sleeves or connectors. 2. The temperature detection sensor for the distribution board is installed in close contact (touch) parallel to the wires of each circuit in the distribution board. 3. The temperature detection sensor for the distribution board is installed in close contact (touch) with the control devices (such as Mg, S/inverters) and load devices of each circuit in the distribution board. 4. For example, in the case of wires, when abnormal temperatures occur due to overload current, faulty electrical equipment, or poor wire connections, the temperature detection sensor attached to the wire detects the abnormal temperature and alerts through an alarm or similar device. 6. In this way, abnormal temperatures of the wires and control devices or load devices in each circuit of the distribution board can be continuously monitored, allowing for early detection and initial response to prevent equipment damage or fire. Maintenance management can be performed reliably and safely. [Note 1]: The temperature detection sensor is integrated with a shape memory alloy combined with the wire, utilizing the softening of the wire and the recovery of the shape memory alloy to create a short circuit (contact) between the two wire cores, thereby detecting the maximum allowable temperature and generating a signal. The set temperature corresponds to the maximum allowable temperature of the wire (80℃).

This device combines a temperature sensing wire (80°C) with a small alarm panel to monitor and alert for abnormal temperatures in distribution board equipment. When the power lines or control lines wired within the wiring duct of the distribution/control panel equipment generate abnormal temperatures (excessive heat) due to overload, poor connections, or equipment failure, the temperature sensing wire detects this and activates the small alarm panel to notify. Additionally, it is possible to alert the administrator via external output terminals. It is a simple and accurate eco-technology product with zero standby power due to its switching function, and the temperature sensing wire uses shape memory alloy, ensuring permanent memory without rust, allowing for long-term use. It complies with the fixed temperature type detector standard (120 seconds) as specified by fire safety regulations. ■ Contact information regarding this matter 2-2-8 Minami Tsutsujigaoka, Kameoka City, Kyoto Prefecture, 621-0847 Space Works Contact: Wada wadakame@siren.ocn.ne.jp TEL: 0771-25-3430 / FAX: 0771-25-4932

This product is a temperature sensing wire with a set temperature of 80°C. It is a product that integrates a large number of shape memory alloys at equal intervals along an extended electric wire, which is attached to the electric equipment's wiring using spiral tubes, monitoring abnormal temperatures caused by overload current in the wire or poor connections, as well as abnormal temperatures due to faults in electrical equipment. It enables safety management of electrical equipment even for those who are not electrical engineers. When the surrounding temperature reaches the set temperature (80°C), the two wires short-circuit to sense the temperature, triggering a mechanism to detect abnormal temperatures as a signal. It utilizes the softening of the wire and the recovery of the shape memory alloy. With permanent memory and no rust, it retains its function indefinitely once activated and can be used for many years. Additionally, it is a non-reset type that allows for confirmation after activation, is simple and easy to use, has good accuracy, and features zero standby power due to its switching function. It excels in environmental performance and complies with the performance standards of type 1 fixed temperature detectors (120 seconds) as stipulated by fire safety regulations. ■ Contact information regarding this matter 2-2-8 Minami Tsutsujigaoka, Kameoka City, Kyoto Prefecture, 621-0847 Space Works Contact: Wada wadakame@siren.ocn.ne.jp TEL: 0771-25-3430 / FAX: 0771-25-4932
