Ambient temperature refers to the temperature of the air or other medium surrounding the equipment or component. Under normal circumstances, the ambient temperature for equipment operation should be -20 to 40 ℃. In such cases, no additional ambient temperature marking is required. However, when the equipment is expected to be used in an environment outside […]

In the operation of enterprises, warehouse management plays a very important role and is the cornerstone of ensuring the continuous stability of product quality. Once problems occur, it will directly cause economic losses and even bring adverse effects to the brand. Now let’s talk about those things in warehouse management that cannot be ignored. The

It is well known that the protective performance of the equipment enclosure protected by the dust-proof ignition-proof enclosure “t” is a key point that product design focuses on. Therefore, the structural rationality of the gaskets and seals that play a protective role is particularly important. I. Structural Requirements In the mating surfaces, compressed gaskets can

The encapsulated type involves completely enclosing the components that may generate sparks or heat capable of igniting explosive mixtures within a compound or a non-metallic casing with adhesive bonding, ensuring that they cannot ignite dust layers or explosive environments under operating or installation conditions. The above is the definition of potting type. In simple terms,

Devices that produce sparks under normal operating conditions specifically refer to equipment that generates arcs and sparks under normal operating conditions. Their electrical clearances and creepage distances comply with industrial safety standards, ensuring reliable insulation distances. For instance, switches, relays, and contactors without explosion-proof protection measures. When such electrical equipment is applied in Zone 2

In explosive hazardous environments, the exposed non-charged metal parts of electrical equipment such as the metal enclosures, metal frameworks, equipment installed on grounded metal structures, metal piping and its fittings, cable protection conduits, and the metal sheaths of cables, etc., should all be grounded. Many standards have made clear regulations on the grounding requirements for

The insulation dielectric strength of “n” type electrical equipment to ground or frame shall comply with the following provisions, except when the circuits installed in the electrical equipment are directly connected to the equipment frame or connected to the frame during equipment operation: a. Tests as specified in the relevant industrial standards for the various
