Introduction

Cables for shipboard fixed electrical systems are widely used in the power supply, control, and instrumentation of shipboard electrical installations, in addition to meeting the requirements of the electrical systems.

In addition to the basic requirements, installation requirements must also be met in the specific environment of a ship. Therefore, it is necessary to establish a selection and installation guidelines for cables used in ship electrical systems.

Standardized system.

GB/T 13029 "Marine Electrical Installations" aims to establish general guidelines for the selection and installation of marine cables, and is proposed to consist of three parts.

constitute.

---Part 1: Cable Selection and Installation. The purpose is to specify the rated voltage (U) of 15kV and below for fixed electrical systems on board.

Requirements for the selection and installation of the downstream cable.

---Part 2: Selection and Installation of Coaxial Flexible Cables. The purpose is to specify the requirements for the selection and installation of marine coaxial flexible cables.

---Part 3: Selection and Laying of Communication and Radio Frequency Cables. The purpose is to specify the selection and laying of marine communication and radio frequency cables.

Selection and laying requirements.

GB/T 13029.1 is a guiding standard for the selection and installation of cables for fixed electrical systems in ships. This document's revision not only conforms to...

This approach is based on my country's actual situation and is conducive to promoting the development of my country's marine cable and shipbuilding industries, as well as aligning with international standards.

Marine electrical installations Part 1: Cable Selection and Installation

1 Scope

This document specifies the basic requirements for the selection and installation of cables with a rated voltage (U) of 15kV and below for fixed electrical systems on board ships.

The fixed systems described in this document include those systems subjected to vibration (due to the vibration of the ship) or motion (due to the motion of the ship), but not...

This includes systems that experience frequent bending. Cables suitable for frequent or continuous bending are specified in detail in other IEC standards, such as...

IEC 60227 and IEC 60245 stipulate that their use on ships is limited to situations where there is no direct exposure to the marine environment, such as portable tools or household appliances.

Electrical appliances.

This document does not include the following types and uses of cables.

---Fiber optic cable;

---Submarine cables and umbilical cables;

---Data, telecommunications, and radio frequency cables;

---Selection and installation of cables for offshore installations.
