Abstract: According to the miniaturization requirements of medium voltage switchgear on offshore platforms， based on the solid insulated switchgear technology， a series of removable products suitable for offshore oil and gas field environment are developed. This paper introduces the technical parameters， overall scheme and key technologies of this kind of products in detail. Through type test and third-party certification， the product can fully meet the needs of offshore oil and gas fields， and provide a new mediumvoltage switchgear solution for the miniaturization and lightweight design of marginal oil fields， modified expansion platforms， deep-water floating platforms， etc.

Key words: offshore platforms, removable, solid insulated cabinet, switchgear
