Properties and application

special temperature label for passenger railway wire and cable (SWX series)

Special temperature label for passenger railway wire and cable (SWX series) is manufactured in accordance with the TJ/CL442-2015 "Temporary Technical Conditions of Special Thermometric Label for Passenger railway wire and cable" issued by China Railway Corporation, which has the unique color-changing temperature display, digital display, adhesive sticker and widely used in the connection parts of air-conditioned train (including high-speed rail, bullet train and subway) control cabinet (distribution cabinet, electrical control cabinet, air conditioning control cabinet, power conversion box, lighting control box), circuit breakers,contactors, thermal relays and fuses to the wire and cable, used to monitor the temperature in connection site.

Once the temperature monitored reaches or exceeds the rated temperature of temperature label, it will be immediately changed from white to black, and the temperature label will also display the concrete number of over-temperature in case of large temperature change. The temperature change of special temperature label for passenger railway wire and cable is irreversible, so it is easy to be found in the inspection process, so that repairers can identify the hidden trouble and prevent the occurrence of accident.

The special temperature label for passenger railway wire and cable manufactured by our company has good softness and strong adhesion, which can be pasted solidly even in the small wire and cable cylindrical surface.

Usage 

1. Special temperature label for passenger railway wire and cable (SWX series) is in the form of labels, and as long as the appropriate rated temperature is selected, it can be directly pasted in the connection points to the control cabinet wire and cable in air-conditioned trains 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: Paste the temperature label in case of no electricity in the wire and cable or other monitoring parts according to safety regulations.

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 5 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.
