The first-ranked distribution cabinet models are: P-type low-voltage switchgear and G-type low-voltage switchgear.
Second digit: g – fixed type, c – withdrawable type, H – fixed type, withdrawable hybrid type.
Third place: L (or D) – power; k – control; s – Senyuan Electrical Systems. GGD is more affordable, while GCS and GCK are more economical.
Example: GGD/M/J①②③g – AC low-voltage distribution cabinet; g – fixed installation and fixed wiring of electrical components; d – power supply cabinet; M – panel operation; J – static capacitor; ① – design sequence number:
1. Breaking capacity: 15 kA; 2. Capacity: 30 kA; 3. Interrupting capacity: 50 kA ②—Main circuit scheme code ③—Auxiliary circuit scheme code
2. Detailed Explanation of Distribution Cabinet Drawings When we typically observe power supply to multi-unit residential buildings, the majority are served by a single distribution cabinet. A simplified internal wiring diagram is as follows: Low-Voltage Distribution Cabinet Single-Line Diagram.
3. The wiring diagram of the distribution panel is divided into the main circuit schematic and the auxiliary circuit schematic: the main circuit schematic depicts the main power circuit, while the auxiliary circuit schematic depicts the control circuit. Intelligent distribution cabinet diagram.
4. Identification: Distribution cabinets GCK, GCS, and MNS are all low-voltage withdrawable switchgear; GGD, GDH, and PGL are low-voltage fixed switchgear; XZW is a comprehensive distribution cabinet; ZBW is a packaged substation; XL and GXL are low-voltage distribution cabinets and construction-site boxes; JXF is an electrical control box; PZ20 and PZ30 series are terminal lighting distribution boxes; PZ40 is an XDD (R) metering box, and PXT (R) K □/□□/□□□□-□/ IP series are standardized model specifications. Explanation: (1) PXT distribution box, concealed installation + (R).
(2) Connection methods for the K series are shown in Table 1.
(3)□/□ Rated current/Rated short-time withstand current: The figures are expressed as 250/10, meaning a rated current of 250 A and a rated short-time withstand current of 10 kA; these values can be reduced upon customer request.
(4)□/□ Input type: □/1 Single-phase input; □/3 Three-phase input; 1/3 indicates mixed input (5)□×□ Output circuits: single-phase circuit × three-phase circuit, 6×3 single-phase with 6 circuits, three-phase with 3 circuits (6)□/□ Main switch type/protection rating: 1/IP30 single-phase main switch/IP30; 3/IP30 three-phase main switch/IP30 Table 1: Explanation of numbering with Chinese pinyin prefixes—assembly drawing number and electrical schematic diagram number. 1 JL Metering Box PXT01 PXT01 dq series 2 CZ Socket Box PXT02 PXT02 dq series 3 ZM Lighting Box PXT03 PXT03 dq series 4 DL Power Supply Box PXT04 PXT04 dq series 5 JC Metering Box PXT05 PXT05 dq series Lighting Box PXPQ series Lighting Box Metering Box PXT08 PXT08 dq series 9 DC Power Socket Box Distribution Cabinet AP Low-voltage Lighting Distribution Cabinet AL Emergency Distribution Cabinet APE Emergency Lighting Distribution Cabinet ALE Low-voltage Load Switch Cabinet AF Low-voltage Capacitor Compensation Cabinet ACC or ACP DC Distribution Cabinet AD Operation Signal Cabinet AS Control Panel Cabinet AC Relay Protection Cabinet AR Metering Cabinet AW Excitation Cabinet AE Low-voltage Residual Current Circuit Breaker Cabinet ARC Dual-circuit Automatic Switch Cabinet AT Multi-circuit Distribution Cabinet AM Knife Switch Cabinet AK Power Socket Box AX Building Automation Controller Box ABC Fire Alarm Controller Box AFC Equipment Monitoring Box ABC Household Wiring Box ADD Distribution Room Duty Robot Introduction

Zhenjiang Ximenzi Hosts a Knowledge Competition
A total of nine teams from various departments took part in this competition. After nearly an hour of intense rivalry, the first-, second-, and third-place awards, as well as the Gold Medalist Award, were ultimately presented.
Zhenjiang Ximenzi Conducts EHS Professional Knowledge and Internal Trainer Training
On December 12, Zhenjiang Siemens invited a professional instructor from Shanghai Qian’an Environmental Protection Company to deliver EHS (Environment, Health, and Safety) expertise training and internal trainer development sessions. More than 20 participants, including heads and supervisors of the Production Department, equipment administrators, and selected frontline employees, attended the training. The curriculum covered mechanical safety safeguards, hazard identification, and risk assessment, with an introduction to practical tools such as energy control and lockout/tagout procedures. During the session, the instructor enhanced trainees’ understanding of how unsafe behaviors lead to accidents by showing short animated videos on behavioral safety. This training marked the first phase of the company’s EHS program; going forward, Zhenjiang Siemens will implement a comprehensive EHS training plan as scheduled to further elevate the company’s EHS management standards.
