As a national business card representing China's speed, China's high-speed rail has developed rapidly in recent years, and its technology is in a leading position in the world. High-speed rail has greatly improved people's travel efficiency and made our lives more convenient.
Rail transportation traction technology is the core of high-speed rail, and traction motor is the creator of this core power. The reliability and life cycle of traction motors are largely related to its insulation. In reality, the traction motor operates in the open air, and the environment is harsh, often affected by wind, sand, rain and snow. The altitude and ambient temperature of the operating area vary widely. The humidity, salinity (hot season in the seaside area) and dust content in the air They are also different. These can make the insulation of the motor worse. Half of all the faults of the traction motor are caused by the damage of the insulation parts. Therefore, the insulation structure of the traction motor should use high-grade insulation materials, which must have good dust resistance, moisture resistance, chemical resistance and excellent thermal stability, and can be repeatedly resistant to electrical, thermal, mechanical, chemical corrosion and environmental changes. The adverse effects.
Based on these demanding requirements, Rogers ARLON® self-melting silicone tape is the ideal choice for the insulation system of rail transit motors.
Why choose ARLON® self-melting silicone tape?
Excellent dielectric strength
ARLON® self-melting silicone tape has an extremely wide operating temperature range (-54 ° C to + 260 ° C, that is, -65 ° F to + 500 ° F), which can provide excellent dielectric insulation performance at 180 ° C ( 356 ° F), its dielectric strength is at least 300 VPM, and it can be used in any place where electrical insulation is required.
2. High insulation
Resistance to moisture, oxygen, ozone, mechanical shock and corona.
3. Good anti-vibration performance
In the transportation industry, vibration is omnipresent. The elasticity of silicone not only keeps the silicone from cracking, but also has the function of reducing vibration and noise
4. Excellent thermal stability
ARLON® silicone can be used for a long time below 250oC. Can withstand 300oC for a short time
5. Low water absorption
ARLON self-adhesive silicone tape can prevent water from penetrating key parts of the motor, avoid short circuit currents, and extend the service life of the machine.
6. High self-adhesive strength for easy winding
At the beginning of the contact of the tape surface, only the molecular chain of the silica gel was dispersed and entangled at the interface. After about one hour, a chemical reaction occurred at the bonded interface. Even tightly wrapped around complex shapes, smooth and even.
The 30 (SA) and 40 (SB) series of MOX tapes® provide uniform thickness even when wrapped around sharp edges.
7. Safe and non-toxic
Our self-adhesive silicone tape does not contain any chemicals that are harmful to the human body. Even if the silicone burns, it will not release toxic chemicals.
8. Flame retardancy
The tape itself has inherent flame retardant properties; non-conductive ash is generated when burned. Meets FAR 25.853 lateral combustion test standards.
Because of the above-mentioned many excellent properties, Rogers ARLON® self-melting silicone tape is widely used in traction motors of high-speed rails, which provides excellent insulation protection for the motors and strongly guarantees the safe and stable operation of high-speed rails.
