Pure Iron Core For Railway Signalling Relays
Products Description
This Pure Iron Core for Railway Signalling Relays, as a core component of the electromagnetic system, undertakes signal conversion and stable transmission functions, meeting the stringent requirements of reliability, magnetic performance, and durability in the railway signaling control field.
The accuracy and safety of railway signaling systems depend on the stable operation of electromagnetic relays. The Pure Iron Core, as the core of the relay's electromagnetic circuit, directly affects signal switching efficiency and anti-interference capabilities. Our products are developed based on the special operating conditions of railway signaling scenarios (high-frequency operation, wide temperature range, strong electromagnetic interference, etc.), providing system integrators with plug-and-play standardized/customized core solutions, covering diverse needs from traditional relays to intelligent signal control devices.
Key Selling Points
High Permeability and Low Remanence
The DT4C AC Relay Iron Core boasts 30% higher permeability than ordinary iron cores and a remanence of less than 0.5mT, significantly reducing relay operation delay and improving signal switching speed.
Optimized Structure through Cold Heading Process
Relay Core Cold Heading technology enables an integrated core design, reducing assembly errors and enhancing mechanical strength.
Corrosion-Resistant Surface Treatment
Relay Core Nickel Plating with Copper Undercoat extends the core's lifespan to over 10 years in humid and salt spray environments, meeting the stringent outdoor environmental requirements of railways.
Product Details
The Coil Soft Iron Core features a high-precision cylindrical shaft structure. Both end faces are fully precision-ground, smooth, and burr-free. The outer cylindrical surface exhibits uniform and smooth cutting marks. Dimensional tolerances are controlled at the micron level throughout the process, ensuring smooth assembly without jamming or gap deviation.
The Coil Core for Electromagnetic Relays features a uniform and dense metal surface with strong adhesion, eliminating the risk of peeling or flaking. It maintains a stable appearance and substrate performance even under long-term conditions of high humidity, dust, and temperature fluctuations along railway lines.
The entire rod has a slotless, stepless, and irregularly shaped structure, conforming to the standard Pure Iron Rod for Relay straight core, suitable for both horizontal and vertical relay installation spaces.
Competitive Advantages
Base Material Advantage
Most competing products use ordinary carbon steel instead of pure iron. Pure Iron Core uses a dedicated DT4C high-purity pure iron base material, offering superior magnetic performance, response speed, and loss reduction, fundamentally solving the relay lag problem.
Process Advantage
Most competing products on the market use ordinary turning machining. This product uses a Relay Core Cold Heading integrated cold heading process, resulting in higher structural strength, better dimensional consistency, and no stress loss in the internal magnetic circuit.
Protection Advantages
While competing products only offer a single nickel plating, the Nickel Plating Relay Core features a unique copper-based nickel-plated double-layer coating, offering superior corrosion resistance, weather resistance, and adhesion compared to single-layer coatings, making it suitable for the harsh outdoor environments of railways.
Compatibility Advantages
Standardized, universal size design allows direct replacement of the cores of most imported and domestic railway signal relays on the market, eliminating equipment modification costs and providing maximum replacement compatibility.
