1Overview This product is made by thickening synthetic lubricating oil with special thickening agent and adding various additives such as corrosion resistance.
-01 High Voltage Circuit Breaker Insulation Grease is mainly used for insulation, protection and sealing of rolling switches. It can also be used for insulation, protection, sealing and lubrication of electrical switches, precision machinery, instruments and instrumentation. Use temperature range 2 Main physical and chemical properties Project quality index Test method Level 1 breakdown voltage (factory) (2.5mm, flat) / kV 30 3 Main features Common circuit breaker oil is based on petroleum distillate, alkali and solvent refined Made of mineral oil. It has the advantages of low flash point and flammability, easy oxidative discoloration, water absorption and rapid decline of insulation performance; easy to lose, volatilize and must be replenished or even replaced at regular intervals (six months to one year). Increased the difficulty and cost of maintenance and maintenance of the circuit breaker.
These shortcomings are especially difficult to overcome, especially in automatic control circuit breakers that are used in difficult to maintain environments.
Synthetic oil is absolutely green: oil is superior in its demanding electrical equipment with high requirements and harsh environment.
7302 grease is a synthetic oil based oil, which has no loss, low evaporation, high flash point (greater than 300), low freezing point (-55), easy to absorb water, etc., so it can be used in a wide temperature range. use. In particular, its excellent oxidation resistance is unmatched by ordinary circuit breaker oil. In the PDSC oxidation induction period test: 25, 70 transformer oil is completely oxidized at 210 minutes and 0.5 MPa oxygen pressure at 1 minute and 3 minutes respectively; and 7302 electrical insulating grease under the same conditions, 30 minutes. It does not oxidize and does not oxidize even at 280. This shows the difference in their oxidation resistance, and this property plays the most critical role in the service life (or cycle) of the insulating material.
In addition, the corrosion resistance and insulation properties of 7302 grease can also reach the standard of circuit breaker oil and are more stable than circuit breaker oil.
At present, 7302 has been adopted by nearly 20 switch factories in China, and its use effect is very good and has been widely recognized.
