In hazardous industrial environments such as petroleum, natural gas, mining, and chemical industries where flammable and explosive gases or dust exist, electrical safety of equipment is crucial. Explosion proof slip ring, as a high safety and high reliability rotating connection device, is specially designed for such explosive environments to ensure that it does not become a detonation source while transmitting power and signals.
Jiujiang Ingiant Technology Co., Ltd., with its profound technical accumulation and rich development and production experience in the field of explosion-proof slip rings, can provide customers with one-stop services from standard products to customized solutions. The products have been certified by the national authoritative explosion-proof organization and are committed to safeguarding the safe operation of high-risk industries worldwide.
Ⅰ. Classified by explosion-proof type
Explosion proof type (Ex d): This is our most core explosion-proof type. The product will completely enclose components that may generate sparks or arcs within a sturdy casing. The shell can withstand internal explosions without damage and effectively prevent flames from spreading to the external environment. Our explosion-proof products are electrical equipment suitable for Class IIC environments and can cover the usage conditions of Class IIA and IIB equipment. Some of the product cases we have worked on include DHK195F-20 and DHS150F-4-100A. You can click on the hyperlink to browse more product information.
Dust explosion-proof type (Ex t): specially designed for explosive dust environments (such as metal dust, coal powder, agricultural and sideline product dust, etc.). By optimizing the structural design, the intrusion of explosive dust is effectively prevented, and the anti explosion and explosion-proof capabilities of the equipment are improved. Some of the product cases we have worked on include DHK038F-22-10A. You can click on the hyperlink to browse more product information.
Intrinsic safety type (Ex i): By limiting the energy of the circuit, it ensures that it does not generate sparks or thermal effects sufficient to ignite ambient gases under normal operation and fault conditions, fundamentally guaranteeing safety. Some of the product cases we have worked on include HDC15-29. You can click on the hyperlink to browse more product information.
In addition, our explosion-proof slip ring can meet the dual requirements of explosive gas environment and explosive dust environment, and is suitable for more complex hazardous working conditions.
Ⅱ. Classified by structural form
DHK through-hole: The center of the slip ring is equipped with a through hole, which facilitates the installation of hydraulic, pneumatic, or transmission shaft components. This type of product has a wide range of applications and can provide multiple specifications for different aperture sizes (such as 12.7mm to 165mm, etc.).
DHS Capsule: With a compact appearance and high design accuracy, it is suitable for precise signal transmission in small and medium-sized systems.
Pancake: A flat design designed to provide a solution for situations where axial installation space is limited.
High current type: designed for high-power application scenarios such as welding, electroplating, generator sets, cable reels, etc., capable of carrying high current transmission.
Customized type: It can combine multiple media such as power, signal, data, optical fiber, etc. according to the special needs of customers, and provide customized functions such as high speed and high temperature resistance.
Ⅲ. Classified by explosion-proof level
Explosion proof rating is a key indicator to ensure the safe use of equipment in specific hazardous areas. Our products cover the following core ratings:
Gas group: The product reaches the IIC level, which is the highest gas group and can be used under both IIA and IIB equipment conditions.
Temperature group: T6 group provides the highest safety level, with the highest surface temperature of the equipment not exceeding 85 ℃, which can meet the requirements of all temperature group environments from T1 to T6.
Equipment Protection Level (EPL): Provides Gb (high protection level, suitable for Zone 1 and Zone 2) and other level products.
Protection level (IP): Provides multiple high protection levels such as IP66, IP67, and even IP68 to ensure stable operation in harsh dust and waterproof environments.
Explosion proof markings such as “Ex d IIC T6 Gb” clearly indicate that the product is explosion-proof, suitable for IIC gas environments, with a maximum surface temperature that meets the T6 group and a high protection level (Gb).
