characterized by high temperature, high humidity, flammability and explosiveness. The safety and reliability of their electrical connections are directly related to production safety, equipment stability and personnel safety. Especially during the operation of the reactor, flammable and explosive media inside the reactor are prone to volatilization, forming an explosive dangerous gas environment. At the same time, dust, water vapor and other substances in the production process put extremely high requirements on the explosion-proof, flame-retardant, dust-proof and waterproof performance of electrical connectors. Ordinary connectors are prone to hidden dangers such as poor contact and short-circuit ignition, becoming “time bombs” in production.

Ankeno, deeply engaged in the field of high-end precision connectors, has accurately identified the connection pain points of chemical reactors. Its independently developed Ex d explosion-proof and flame-retardant electrical connectors, relying on comprehensive protection performance and stable connection performance, have been successfully applied to the reactor systems of many chemical enterprises, building a solid safety line of defense for high-risk production scenarios and helping production proceed efficiently and orderly.

A large fine chemical enterprise uses its reactors mainly for the production of flammable organic compounds. During the production process, it is necessary to real-time monitor parameters such as temperature and pressure inside the reactor, and at the same time ensure the power transmission of the stirring motor and control system. The ordinary connectors used previously frequently had problems such as poor contact and protection failure, which not only led to equipment shutdown and affected production efficiency, but also posed great safety hazards. A special connector suitable for this harsh working condition was urgently needed.

To meet the core needs of the enterprise, Ankeno customized an Ex d explosion-proof and flame-retardant electrical connector solution for it, which perfectly meets the stringent use requirements of chemical reactors. In terms of explosion-proof performance, the product strictly complies with the national standards GB3836.1-2010 and GB3836.2-2010, with an explosion-proof grade of Ex db T4 IICT6 Gb. It can operate safely in Zone 1 and Zone 2 explosive gas environments containing IIA, IIB and IC categories of T6 temperature group, effectively isolating internal electric sparks and high temperatures, eliminating the risk of igniting external flammable and explosive media, and avoiding safety accidents from the source.

Considering the humid and dusty characteristics of the reactor production environment, the connector has an IP66 protection level, paired with a flame-retardant rubber sealing ring, which can effectively resist dust intrusion and water immersion impact. Even in a high humidity environment of 90%-95% and a temperature range of -55℃ to +60℃, it can maintain stable operation, avoiding connection failures caused by environmental factors. At the same time, the product adopts a 316L stainless steel shell, which is corrosion-resistant and anti-aging, adapting to the corrosive media around the reactor and greatly extending the service life.

In terms of connection performance, the connector adopts a high-reliable hyperboloid wire spring jack, which has soft insertion and extraction and small contact resistance, ensuring stable transmission of power and signals, and avoiding problems such as monitoring data deviation and equipment shutdown caused by poor contact, thus ensuring precise control of reactor process parameters. The plug and socket support two termination methods: welding and crimping, which can be flexibly selected according to on-site installation needs. It also has a five-key positioning function to realize blind insertion and anti-mismating, effectively avoiding safety hazards caused by misoperation. At the same time, the thread-type quick connection design greatly improves installation and maintenance efficiency.

Since the connector was put into use, it has completely solved the safety pain points of electrical connection of the enterprise’s reactors, greatly reduced the number of equipment shutdowns, increased production efficiency by more than 30%, and no safety hazards caused by connector failures have occurred, winning high recognition from the enterprise. At present, Ankeno Ex d explosion-proof and flame-retardant electrical connectors have been widely used in high-risk fields such as chemical reactors, oil drilling and natural gas extraction. With customized solutions and high-reliable product performance, they have become the preferred product for safe connection in the chemical industry, safeguarding high-end chemical production.
