As an environmentally friendly and efficient new energy utilization method, biogas power generation has been widely applied in scenarios such as farms and sewage treatment plants. Its core is to convert biogas generated by anaerobic fermentation into electrical energy, realizing the transformation of waste into valuable resources. However, explosive hazardous gases such as methane exist for a long time in areas such as biogas tanks and valve wells of biogas power plants, coupled with a humid and dusty environment, which puts extremely strict requirements on the explosion-proof, dust-proof and waterproof performance of electrical connection equipment. The application of Ankeno Ex e type increased-safety explosion-proof and flame-retardant electrical connectors has built a solid connection line of defense for the safe and stable operation of biogas power plants.

A biogas power station supporting a large-scale farm has a designed installed capacity of 30 kilowatts, mainly treating biogas generated from manure and sewage of the farm, with an annual power generation capacity of up to 130,000 kWh. It can not only meet the farm’s own electricity demand but also realize resource recycling. In the early stage of the power station’s operation, due to the use of ordinary connectors, problems such as poor contact and seal failure occurred frequently. There was even a potential safety hazard caused by electrical sparks contacting leaked biogas, which seriously affected power generation efficiency and production safety. To completely solve this pain point, after multiple comparisons, the power station finally selected Ankeno Ex e type explosion-proof and flame-retardant electrical connectors, which are fully applied to the electrical connection of key equipment such as biogas generator sets, gas concentration sensors and circulating pumps.

Combined with the working condition characteristics of biogas power plants, Ankeno Ex e type electrical connectors show strong adaptability and reliability. The product strictly complies with the national standards GB3836.1-2010 and GB3836.3-2010, with an explosion-proof grade of Ex eb IIC T6 Gb, which can perfectly adapt to the explosive hazardous environments of Zone 1 and Zone 2 in biogas power plants. It effectively prevents fire and explosion risks caused by flammable gases such as methane, and meets the compliance requirements for electrical equipment in hazardous areas specified in the EN IEC 60079-14:2024 standard.

In response to the humid and dusty environment of biogas power plants, the connector has an IP66 protection level, paired with a flame-retardant rubber sealing ring, which can effectively block dust intrusion and water penetration, and maintain stable operation even in high-humidity environments. Its shell is made of 316L stainless steel, which can resist corrosion from corrosive gases such as hydrogen sulfide in biogas and extend service life. The contacts adopt copper alloy gold-plating technology, combined with high-reliable hyperboloid wire spring jacks, which not only makes insertion and extraction smooth but also ensures small contact resistance, guaranteeing stable transmission of power and signals and avoiding equipment shutdown caused by poor contact.

In addition, the humanized design of the product greatly improves the operation and maintenance efficiency of the power station. The plug and socket support two termination methods: welding and crimping, which can be flexibly selected according to on-site installation needs; the five-key positioning design has blind insertion and anti-mismating functions, and the thread-type quick connection facilitates installation and maintenance, greatly reducing the work intensity of operation and maintenance personnel. At the same time, the contacts can be flexibly disassembled and assembled, and the socket supports two installation methods: square plate type and mobile type, adapting to the installation scenarios of different equipment in the power station.

Since the biogas power station applied Ankeno Ex e type explosion-proof and flame-retardant electrical connectors, the operational stability of the equipment has been significantly improved. No potential safety hazards caused by electrical connection problems have occurred again, the equipment failure rate has dropped by more than 90%, and the annual downtime loss has been reduced by more than 10,000 yuan. With its technical accumulation in the field of high-end precision connectors, Ankeno provides safe guarantee for harsh environment scenarios such as biogas power plants with customized and high-reliable connection solutions, helping the green and efficient development of the new energy industry.
