intelligent color-changing temperature label (ZCW series) 

Properties and application

Intelligent color-changing temperature label (ZCW series), also known as three-color-changing temperature label, has a unique color temperature display, display and temperature recording function, which has adhesive sticker used in the connection parts of substation bus bars, or pasted to the connection between bus and device terminal and the contacts of disconnecting switch. Moreover, it can also be pasted to the shell of transformer, capacitors, motors and other electrical equipment, used to monitor the temperature of bus connection and electrical equipment shell. Once the monitoring temperature reaches or exceeds the rated temperature, the temperature label will immediately change the color from white to red and displays the over-temperature on the temperature label. The temperature change is easy to be found in the inspection process, so that repairers can identify the hidden trouble and prevent the occurrence of accident.

Color change of intelligent color-changing temperature label:

When the monitoring temperature reaches or exceeds the rated temperature of intelligent color-changing temperature label, the temperature label will immediately change the color from white to red; when the temperature declines below the rated temperature, the temperature label will not restore the original white color, but black, indicating that the rated temperature is exceeded and now the temperature declines below the rated temperature; when the temperature reaches or exceeds the rated temperature again, the temperature label will immediately change the color from black to red; repeated in such a way. The color of temperature label can be changed from white to red, red and black; it can be recycled.

Usage

1. Intelligent color-changing temperature label (ZCW series) is in the form of labels, and as long as the appropriate rated temperature is selected, it can be directly pasted in the bus connector, switch, transformer shell and other parts to monitor the temperature. The pasted sites shall be clean, dry; press firmly when pasted.

2. If you want to know the gradual increase of temperature in the monitoring parts, temperature label with two or more rated temperature points can be pasted; ZCW-6575type can also be used.

3. Note:

a. Paste the temperature label in case of no electricity in the wire and cable or other monitoring parts according to safety regulations. If it is pasted in power, use the appropriate level of insulation stick.

b. Intelligent color-changing temperature label cannot be used in the sun exposure.

Storage and service life 

1. Temperature label shall be stored at room temperature. It is non-toxic and tasteless without stimulation against the skin; place it away from heat (such as radiator and electric furnace).

2. Due to the complexity of application site, temperature label can be used for 4 years in the monitoring parts in case of normal temperature and normal environment. Those with changed color due to over-temperature shall be repaired and replaced timely.
