Cables by Type

Prefabricated Branch Cable

Prefabricated branch cables are specialized electrical cables designed to streamline the process of electrical distribution in buildings and large-scale construction projects. These cables are manufactured with predefined branch-off points and connectors, allowing for quick and efficient installation without the need for on-site cutting or splicing. They provide a reliable and cost-effective solution for distributing power to multiple locations from a single main power source.

Prefabricated branch cables are known for their ease of installation, reliability, and safety. They minimize installation time and labor costs while ensuring consistent quality and performance. These cables are widely used in commercial, industrial, and residential applications where complex wiring systems are required.

Applications

Commercial Buildings: Power distribution in office buildings, shopping centers, and hotels.

Industrial Facilities: Electrical systems in factories, warehouses, and production plants.

Residential Complexes: Multi-unit residential buildings and housing developments.

Infrastructure Projects: Airports, hospitals, schools, and other large-scale infrastructure projects.

Construction

Main Conductor: Typically made of copper or aluminum, providing excellent electrical conductivity.

Insulation: High-grade materials like XLPE (cross-linked polyethylene) or PVC (polyvinyl chloride) to withstand high temperatures and voltages.

Branch Connections: Pre-fabricated branch-off points with connectors that allow for easy and secure connections.

Outer Sheath: Durable and flexible outer sheath made of materials like TPU (thermoplastic polyurethane) or rubber to resist abrasion, chemicals, and environmental factors.

Protection: Additional protection such as fire-resistant or water-resistant sheathing for specific applications.

Cable Types

Standard Prefabricated Branch Cables

1. Construction: Includes copper or aluminum conductors, XLPE or PVC insulation, and pre-fabricated branch-off points with connectors.

2. Applications: Suitable for general power distribution in commercial and residential buildings.

Fire-Resistant Prefabricated Branch Cables

1. Construction: Features fire-resistant insulation and sheathing to maintain circuit integrity in the event of a fire.

2. Applications: Ideal for installations in buildings where fire safety is a critical concern, such as hospitals, schools, and high-rise buildings.

Waterproof Prefabricated Branch Cables

1. Construction: Includes water-resistant sheathing and sealed branch-off points to prevent water ingress.

2. Applications: Suitable for outdoor installations and environments with high humidity or exposure to water, such as tunnels, bridges, and underground facilities.

High-Temperature Prefabricated Branch Cables

1. Construction: Designed with high-temperature resistant materials to operate in environments with elevated temperatures.

2. Applications: Ideal for industrial facilities with high ambient temperatures, such as steel mills and foundries.
