Introduction

GB/T 18233 "General Cabling for Information Technology User Building Complexes" is a standard to guide the design of general cabling systems in specific types of buildings.

GB/T 18233 is based on ISO/IEC 11801.According to ISO/IEC 11801, different building types and scenarios are considered.

GB/T 18233 is proposed to consist of 6 parts.

--Part 1: General Requirements. The purpose is to provide a general design guideline for cabling systems in user building complexes, and to provide cabling solutions for specific locations.

The system design provides a general reference.

--Part 2: Office Space. The purpose is to provide a general design guide for cabling systems in office spaces.

--Part 3: Industrial Building Complexes. The purpose is to provide a general design basis for cabling systems in industrial building complexes.

--Part 4: Residential Buildings. The purpose is to provide a general design guide for cabling systems in residential buildings.

--Part 5: Data Centers. The purpose is to provide a general design guide for data center cabling systems.

--Part 6: Distributed Building Facilities. The purpose is to provide a general design guideline for cabling systems in distributed building facilities.

1 Scope

This document specifies the general cabling requirements for industrial areas within industrial buildings or non-industrial buildings, which may be located in industrial parks.

A single building or a group of buildings. Includes balanced cabling and fiber optic cabling.

This document applies to locations with telecommunications service cabling up to 10,000 m in length. Systems with longer distances can refer to this document for further information.

The cabling system defined in this document supports a wide range of services, including process control, monitoring, and automation services. It may also include power supply services.

This document directly or by referencing the provisions of GB/T 18233.1-2022.

a) Structure and minimum configuration of general cabling for industrial building complexes;

b) The interface of the telecommunications socket (TO);

c) Transmission performance requirements for cabling links and channels;

d) Requirements and options for implementation;

e) Performance requirements for cable installation components;

f) Conformity requirements and acceptance procedures.

Cabling for critical process control, monitoring, and automation services within automation islands is not covered by this document. This type of application-specific cabling...

Cables, design specifications are in IEC 61784-5 (all parts), installation specifications are in IEC 61918.

Safety (electrical safety and protection, fire protection, etc.) and electromagnetic compatibility (EMC) requirements are specified by other standards and regulations and are not included in this document.

Within this scope. The requirements specified in this document are for reference only.
