Conductive rings are the indispensable ‘lifeline’ of modern rotating equipment. They ingeniously solve the challenge of electrical connectivity between rotating and stationary components, enabling the continuous and reliable transmission of electrical power and various information flows across rotating interfaces. From massive wind turbines to precision medical CT scanners, from security surveillance cameras to satellite radars exploring the universe, conductive rings quietly play a critical role, serving as the core foundational components enabling continuous, stable, and intelligent rotational functionality in equipment. Their performance characteristics—such as transmission capacity, signal quality, lifespan, and reliability—directly impact the overall performance of the entire equipment system.
Features of Conductive Rings
1. Contact Materials and Technology: The selection of materials for Morteng brushes and ring tracks (commonly used materials include gold alloys, silver alloys, copper alloys, graphite, etc.) is critical for conductivity, wear resistance, contact resistance stability, lifespan, and cost. Precious metals (gold) are used for high-reliability, low-current signals; silver or copper alloys are used for high-current applications; graphite or metal graphite are used for high-speed or special environments.
2. Wear and Lifespan: Sliding contact inevitably involves wear. Morteng's design objective is to minimise wear while ensuring performance, thereby extending service life (up to millions of revolutions or more). Maintenance-free design is the goal of high-end slip rings.
Electrical Performance of Morteng Conductive Rings:
1. Contact Resistance: Low and stable, with minimal fluctuations.
2. Insulation resistance: High insulation resistance is required between rings and between rings and ground.
3. Dielectric strength: Capable of withstanding a certain voltage without breakdown.
4. Signal integrity: For signal transmission, low noise, low crosstalk, wide bandwidth, and low attenuation (especially for high-frequency signals) are required. Shielding design is critical. It must be able to withstand harsh environments such as high temperatures, humidity, salt spray, dust, vibration, and impact. Sealing performance is very important.
