The new generation YBBP series complies with China's explosion-proof standards GB 3836.1 and GB 3836.2, and its motor performance meets the industry standards for explosion-proof motors in China JBT 11201.1-2011 YBBP series explosion-proof variable frequency speed regulation three-phase asynchronous motors (frame number 80-355), JBT 11201.2-2015 explosion-proof variable frequency speed regulation three-phase asynchronous motors technical conditions Part 2: YBBP series explosion-proof (Ex d II C T1~T4) variable frequency speed regulation three-phase asynchronous motors (frame number 80~355), JBT 11201.3-2015 YBBP-W, YBBP-TH, YBBP-THW series explosion-proof variable frequency speed regulation three-phase asynchronous motors technical conditions (frame number 80~355), and their efficiency and installation dimensions comply with the YBBP series industry standards. Standard and compliant with IEC and national standards, customers can achieve fast switching.

The new generation YBBP series motors have the advantages of large junction box volume, improved safety and reliability, increased capacity, and professional appearance design, greatly enhancing the market competitiveness of explosion-proof motor products.

Leakage into the surrounding environment through cracks in containers or pipelines, sealed joints, operating holes, valves, etc., mixes with the air in the environment, creating an explosive hazardous environment. If there is also an ignition source in the environment, combustion or explosion will occur.

In order to prevent explosion and fire hazards, explosion-proof measures should be taken in the above-mentioned places. Explosion proof measures can be divided into two categories in engineering:
1. Primary explosion-proof measures - to avoid explosive hazardous environments in the workplace.
2. Secondary explosion-proof measures - Avoid ignition sources in explosive hazardous environments. Both national and international standards stipulate that explosion-proof electrical products must be used in explosive hazardous areas to avoid damage to personnel and materials caused by explosions and fires, which is considered a secondary explosion-proof measure.

Explosion proof enclosure type "d" is an explosion-proof type of electrical equipment, whose enclosure can withstand explosive mixtures entering the interior of the enclosure through any joint surface or structural gap without damage, and will not cause ignition of explosive gas environments formed by one or more gases or vapors outside, thereby ensuring environmental safety.
