**Key Points for Duct Cable Installation**

**1. Duct and Conduit Requirements**

The following preparations shall be made before installing the duct cable:

**Conduit Selection Principles:**

- When the design does not specify the conduit position, conduits shall be used layer by layer **from bottom to top and from both sides towards the middle**.

- The conduit positions occupied by the cable in adjacent duct sections shall be relatively consistent to avoid switching from one side of the duct bank to the other.

- The conduit position selected along the same route should not be changed.

**Conduit Cleaning:** Before installation, the conduits shall be cleaned to ensure they are unobstructed.

**2. Sub-duct Installation**

When installing cables in large-diameter plastic ducts, plastic sub-ducts are typically used to improve conduit utilization and protect the cable:

| Item | Requirement |

| Sub-duct Material | Plastic tubing with good durability and environmental compatibility |

| Number of Sub-ducts | The total equivalent outer diameter of several sub-ducts should not exceed **85% to 90%** of the inner diameter of the main duct. |

| Sub-duct Inner Diameter | Should not be less than **1.5 times** the outer diameter of the cable. |

| Installation Method | Multiple sub-ducts within the same main duct shall be installed **in a single pull**. |

| Splice Requirement | Sub-ducts **shall have no splices** inside the main duct. |

| End Sealing | Unused sub-duct ends shall be sealed against water ingress. |

| Color Coding | Multiple sub-ducts within the same main duct should be distinguished by using different colors. |

**Sub-duct Protrusion Length:**

- Within manholes/handholes, the protrusion length of sub-ducts shall be **200mm to 400mm**.

- Within power ducts, the protrusion length of sub-ducts can be **150mm to 200mm**.

**3. Cable Installation Method**

Duct cables can be installed using mechanical pulling or manual pulling:

- The pulling tension for a single pull **shall not exceed the cable's allowable tensile strength**.

- After installation, the cable shall be **free from twisting, crossing, obvious scratches, or damage**.

- The cable **shall not be bent within 150mm** of exiting the conduit.

- At conduit bends or crossings with other obstacles, guiding devices or bell-mouth protective tubes shall be used for protection.

**4. Installation in Manholes/Handholes**

Cable installation within manholes/handholes shall meet the following requirements:

- The cable shall be **secured firmly** and should be protected with a plastic flexible tube (e.g., corrugated pipe).

- Cable splice closures shall be installed above the

year-round water level and supported by protective brackets.

- Cables **shall not pass directly through** a manhole.

- Reserved cable lengths shall be coiled according to bending radius requirements and securely fastened to brackets.

- **Cable identification signs or labels** shall be installed (a signboard shall be placed in every manhole).

- Cable splice closures shall be fixed to pre-embedded fittings on the manhole wall.

**5. Conduit Sealing**

After cable installation, the ends of both the main ducts and sub-ducts shall be sealed tightly as required by the design to prevent the ingress of water, vapor, and debris.
