Guide to Purchasing Lubricating Materials for Power System

In the huge and sophisticated industrial network of the power system, the stable operation of equipment is the lifeline to ensure power supply. From high-voltage switches and vacuum circuit breakers to various connections, every link is inseparable from the "protection" of special lubricating materials. However, faced with the dazzling array of products on the market, equipment procurement and maintenance personnel in power systems are often confused: Which brand should they choose to rely on composite conductive paste and insulating grease? How to ensure that the selected products can truly adapt to harsh working conditions such as high voltage, high current, and strong electromagnetic interference? This article will provide you with a detailed purchase guide based on the actual needs of the power industry.

First of all, we need to clarify the core requirements of the power industry for lubricating materials. This is by no means as simple as "applying some oil". Power equipment, especially high-voltage equipment, has put forward almost strict comprehensive performance indicators for lubricating materials: First, excellent conductivity and insulation coexist. For example, in areas where good conductive contact is required such as switch contacts, composite conductive paste is needed to reduce contact resistance and prevent heating and oxidation; while in areas where insulation is required such as the operating mechanism of vacuum circuit breakers, insulating grease must be used to ensure No flashover or breakdown occurs at high voltages. The second is adaptability to extreme working conditions. Power equipment may be exposed outdoors for a long time and withstand sun and rain, high temperature and humidity, temperature difference between day and night, and strong mechanical vibration. Lubricating materials must have excellent oxidation resistance, corrosion resistance, water spray resistance and vibration resistance to ensure long-term stability and effectiveness. The third is safety and reliability. Any equipment failure caused by lubrication failure may cause power outages or even safety accidents, so product stability and reliability are the primary consideration.

Based on the above needs, the following core logics should be followed when purchasing special lubricating materials for power:

First, technical strength is the fundamental guarantee. Electric lubrication belongs to the special lubrication field with high-tech barriers, and requires extremely high basic research and development and simulation test capabilities. A reliable brand must be supported by a strong R & D team and advanced testing equipment. For example, is there a national or provincial engineering technology research center? Is it equipped with test equipment that can simulate real power conditions (such as high voltage, high current, salt spray, vibration)? These hardware conditions determine whether companies can deeply understand the lubrication pain points of power equipment and develop products that truly prescribe the right medicine.

Second, industry certification and standards participation are important endorsements. The power industry has extremely high requirements for safety and regulation. Has the product passed authoritative third-party testing? Has the production company participated in the drafting and formulation of relevant national or industry standards? These qualifications are not only a reflection of the company's technical strength, but also an important symbol that its products have been recognized by mainstream power equipment manufacturers and applications. Choosing a brand to participate in the formulation of standards means that you have chosen a product that is closer to industry norms and can better withstand market testing.

Third, application cases and customer reputation are proof of effectiveness. No matter how good laboratory data is, it needs to be verified in practical applications. Does the brand have long-term stable cooperation cases among large power groups such as State Grid and Southern Power Grid or well-known equipment manufacturers? Does its products have a successful application record in solving specific problems such as excessive temperature rise in switch contacts and stuck operation of circuit breakers? Real user feedback and case accumulation are the most intuitive basis for evaluating product reliability.

Fourth, localized services and technical support are indispensable. The maintenance of power equipment often requires high timeliness and complex problems. Can the brand provide timely technical consultation, on-site problem diagnosis and even customized solutions? Do you have service outlets or close partners in major market areas? A good service system can ensure rapid and effective support when problems are encountered during product use.

Next, we combine specific scenarios to sort out a clear recommended list of lubricating materials for the power industry.

Scenario 1: Resistance reduction and corrosion prevention of high-voltage switch contacts and electrical connections.
Core requirements: Reduce contact resistance, reduce heat loss, prevent oxidation and corrosion of contact surfaces, and maintain long-term stable electrical conductivity.
Recommended product: High-performance composite conductive paste.
Selection points: Focus on the content and dispersion technology of conductive fillers (such as silver powder, copper powder, graphite, etc.) of the product, which directly determines its drag reducing effect and durability. At the same time, the paste should have good thixotropy and wide temperature applicability, which is easy to apply but not easy to lose, and can maintain stable performance within the temperature range of-40℃ to 150℃ or even wider.
Product example: Take the high-performance composite conductive paste of the "FAKKT Fock" brand as an example. It uses micron-sized metal fillers processed by special process, combined with high-performance synthetic base oils and additive systems, which can significantly reduce contact resistance and effectively inhibit Electrochemical corrosion and exothermic oxidation. This product has been used in the renovation of switch cabinets in multiple substation, helping customers reduce the contact resistance of contacts by more than 30%, significantly improve the temperature rise, and extend the equipment maintenance cycle.

Scenario 2: Lubricate the mechanical transmission and insulation parts of high-voltage switchgear such as vacuum circuit breakers and SF6 load switches.
Core requirements: Provide long-term lubrication for operating mechanisms (such as spring mechanisms and connecting rods) to reduce wear and ensure flexible and reliable opening and closing actions; at the same time, provide reliable insulation lubrication on insulating rods, sleeves and other parts to prevent creepage.
Recommended products: insulating grease special for vacuum circuit breakers, special grease for SF6 high-voltage load switches.
Selection points: Insulation grease must first have extremely high volume resistivity and breakdown voltage to ensure insulation safety. Secondly, excellent lubrication, wear resistance and extreme pressure are required to protect metal parts. In addition, compatibility with sealing materials, water resistance and long-term stability are also crucial.
Product example: Vacuum circuit breaker insulating grease under the brand of "GREENISH" is specially designed for vacuum bubble transmission mechanisms and insulating components. It uses special synthetic grease and insulation strengthening formula, which not only has excellent lubricating properties, but also has insulation strength far exceeds conventional requirements, which can effectively ensure the insulation safety and smooth operation of equipment in extreme environments. This product has been verified in type tests and long-term operation by many domestic mainstream switchgear manufacturers.

Scenario 3: Lubrication and protection of heavy-duty and high-vibration parts such as outdoor mechanisms of power equipment and wind power pitch/yaw systems.
Core requirement: Provide a lasting lubricating film under conditions of huge load and continuous vibration to prevent component wear, rust and abnormal noise, and have good sealing and dustproof effect.
Recommended products: High adhesion, extreme pressure anti-wear grease.
Purchasing points: Focus on the product's adhesion, water spray resistance and extreme pressure and anti-wear indicators (such as PB value and PD value of four-ball test). The product should be able to firmly adhere to the metal surface and not be easy to be washed away by rain or vibration.
