Chbebpower -Zinc oxide arrester is a new type of fully sealed and highly reliable lightning protection device for 10kV power distribution system. It is made of zinc oxide valve column, upper and lower electrodes, and silicone rubber integrally molded. It has the following characteristics: The new structure fundamentally solves the sealing problem of the arrester. The core and jacket of the arrester form a dense whole, eliminating the cavity that causes breathing and solving the technical key to preventing internal components from getting damp. The core has strong ability to withstand internal overvoltage and good aging characteristics. The specially developed valve plate and reasonable core parameters are used to ensure that the core can reliably withstand arc grounding, PT resonance and various operating overvoltages, and can operate safely for a long time under line voltage, 2.5 times and 3 times power frequency overvoltage. The voltage withstand time is 1 to 3 orders of magnitude higher than international requirements.

➡️LDMC Series Large Displacement Jet Pulse #LongBagdustCollector  LDMC series large-displacement blowing pulse long bag dust collector is developed by our company on the basis of blowing pulse dust removal technology to meet the needs of large air volume flue gas purification. It combines the advantages of two kinds of dust collectors, namely, compartmentalised reverse blowing and pulse cleaning, overcomes the shortcomings of compartmentalised reverse blowing with insufficient dust removing strength and general pulse cleaning and re-adsorption, and has a higher dust removing efficiency and a lower blowing frequency. The product adopts submerged pulse valve, which reduces the pressure of blowing air source and energy consumption of equipment operation, prolongs the service life of filter bag and pulse valve, and greatly improves the comprehensive technical performance. Widely used in #buildingmaterials, #electricpower, #metallurgy, #petrochemical, #grain, #iron and #steel, #carbonblack, #rubbishincineration, #industrialkilns and other room temperature or high temperature dusty gas purification and recovery of powdery materials.

🔹 Springs and wire formed parts play a critical role in the performance of various circuit breakers, switches, and electrical relays. Metal wire can be formed to create pathways and connect electrical components within tight spaces. Springs are used, not only in their typical manner, but also to conduct electrical currents when made of materials like copper, steel, or many others!

Subject: Price Factors of Non-Full Pipe Electromagnetic Flowmeters The price of non-full pipe electromagnetic flowmeters is affected by multiple aspects. Structure type impacts it; integrated ones are cheaper than split-types. Material and lining choices matter. Carbon steel is low-cost, while stainless steel and high-performance linings like PTFE cost more. Electrode materials vary in price; 316L is moderate, and special ones for corrosive media are pricey. Connection methods have price differences; flange is common, clamp is convenient but costlier, and insertion-type is relatively inexpensive. Output signal and communication ways play a part; pulse is cheaper than current, and advanced protocols cost more. Higher measurement accuracy and more functions like bidirectional flow and wireless transmission lead to a higher price. Brand and after-sales also influence; well-known brands with good service are more expensive. #NonFullPipeElectromagneticFlowmeter #PriceFactors #FlowmeterDetails

Functional fiber manufacture Alumina continuous fiber  /Continuous alumina fiber Excellent thermal resistance, high strength and modulus, and electrical insulation properties.

Thermal Conductivity of Aluminum Profiles: Aluminum profiles have excellent thermal conductivity, with a thermal conductivity of approximately 205 W/m-K, much higher than many other metals. This make aluminum extrusions very popular for applications that require rapid heat dissipation, such as radiators, heat exchangers and electronic equipment housings. The combination of its light weight and good thermal conductivity makes aluminum profiles ideal for use in thermal management solutions, helping to keep equipment within a safe operating temperature range. #aluminumprofile #aluminumextrusion

Electric insulated bearings is a general term of the bearing which can prevent the current from passing through and has the insulating property，Its insulation performance is usually to process a layer of alumina coating on the outer ring or inner ring of the bearing by using the international advanced technology to withstand the voltage DC，It is generally divided into inner ring coated insulated bearing and outer ring coated electrically insulated bearing. Its basic coating can withstand voltage up to 1000 V DC. Its code adopts international bearing code.
