High-voltage Distribution Panel Recycling Product Categories:
Breaker by type
Circuit breakers are categorized by installation type into withdrawable (handcart type) and fixed types.
(1) Withdrawable or Handcart Type (represented by Y): Indicates that the main electrical components (such as circuit breakers) inside the cabinet are mounted on a removable handcart. Due to the high interchangeability of the handcart cabinet, it significantly enhances the reliability of power supply. Common types of handcart include isolation handcart, metering handcart, circuit breaker handcart, PT handcart, capacitor handcart, and transformer handcart, etc., such as KYN28A-12.
(2) Fixed Type (represented by G): Indicates that all electrical components inside the cabinet (such as circuit breakers or load switches, etc.) are installed in a fixed type. Fixed type switch cabinets are relatively simple and economical, such as XGN2-10, GG-1A, etc.
As location
Indoor and outdoor, as categorized by installation location
(1) For indoor use (denoted as N); indicating that installation and use are restricted to indoor settings, such as: switch cabinets like KYN28A-12;
(2) For Outdoor Use (indicated by "W"); signifies that the product can be installed and used outdoors, such as: XLW switch cabinets.
As per cabinet structure
Switchgear cabinets can be categorized into four main types: metal-enclosed armored switchgear, metal-enclosed interval switchgear, metal-enclosed box switchgear, and open-type switchgear.
(1) Metal-enclosed armored switchgear (represented by the letter K) mainly consists of components such as circuit breakers, transformers, busbars, etc., which are individually housed in metal-enclosed switchgear within compartments separated by grounded metal partitions. For example, the KYN28A-12 type high-voltage switchgear.
(2) The metal-enclosed switchgear with separated compartments (represented by the letter J) is similar to armored metal-enclosed switchgear. Its main electrical components are also mounted in separate compartments, but it features one or more non-metallic partitions that meet the protection grade. For example, the JYN2-12 type high-voltage switchgear.
(3) Metal-enclosed switchgear cabinets (represented by the letter X) are switchgear devices with a metal-enclosed cabinet shell. For example, the XGN2-12 high-voltage switchgear cabinet.
(4) Open-type switch cabinets without specific protection grade requirements; the housing features partially exposed switch equipment. Such as the GG-1A(F) type high-voltage switch cabinet.
