reversible color-changing temperature label (NCW series) 

Properties and application

Reversible color-changing temperature label (NCW series) has a unique color temperature display, reflective 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 black 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.

If the temperature monitoring parts are in high temperature, the  temperature label will immediately change the color; it will immediately restore the original color once cooled, so that the label can continue to be used.

Reversible color-changing temperature label generally changes the color from black to red, but other colors can also be chosen (customized);

Usage

1. Reversible color-changing temperature label (NCW 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.

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. Reversible 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 3-4 years in the monitoring parts in case of normal temperature and normal environment.
