Multi core cable model specification table 15x1.5 square meters is a widely used cable in the telecommunications industry. It is known for its high performance and reliability, making it an ideal choice for various applications. In this article, we will explore the specifications of this cable from four different aspects: conductor material, insulation material, outer sheath material, and voltage rating.

1. Conductor Material

The conductor material used in multi core cable model specification table 15x1.5 square meters is typically copper or aluminum. Copper conductors offer excellent conductivity and are commonly used in cables that require high transmission speeds and low signal loss. Aluminum conductors are lighter and more cost-effective but have slightly higher resistance compared to copper.

The size of the conductor is specified as 15x1.5 square meters, which means that each individual core has a cross-sectional area of 1.5 square millimeters (mm²). This size ensures sufficient current carrying capacity while maintaining flexibility for easy installation.

In addition to the conductor size, the number of cores also plays a crucial role in determining the overall functionality of the cable. The multi-core design allows multiple signals or power lines to be transmitted simultaneously within a single cable.

2.Insulation Material

The insulation material used in multi core cables provides electrical isolation between conductors as well as protection against external factors such as moisture and temperature variations.

Polyvinyl chloride (PVC) is commonly used as an insulation material due to its excellent electrical properties and affordability. PVC-insulated cables are suitable for indoor applications where they are not exposed to extreme temperatures or harsh environments.

For outdoor or industrial applications that require higher resistance against environmental factors like UV radiation or chemicals, cross-linked polyethylene (XLPE) insulation may be preferred over PVC insulation due to its superior durability and thermal stability.

3.Outer Sheath Material

The outer sheath of multi-core cables provides mechanical protection against abrasion, impact, moisture ingress, and other external hazards encountered during installation or operation.

PVC is commonly used as an outer sheath material due to its flexibility and ease of processing during manufacturing. However, if additional protection against fire hazards is required by building codes or regulations, flame-retardant PVC (FR-PVC) can be chosen instead.

In some cases where enhanced mechanical strength or resistance against oil/grease exposure is needed - such as industrial environments - polyethylene (PE), low-smoke zero-halogen (LSZH), ethylene propylene rubber (EPR), chlorosulfonated polyethylene rubber(CSPR), etc., may be selected based on specific requirements.

4.Voltage Rating

Voltage rating refers to the maximum voltage at which a cable can safely operate without risk of breakdowns or failures. The voltage rating for multi-core cables varies depending on their application requirements. Typically these typesofcablesareavailableinbothlowvoltage(LV)andmediumvoltage(MV)rangingfrom250Vto1000VforLVandupto35kVinMVapplications.The appropriate voltage rating should always be considered when selecting a multi-corecabletoensureitscompatibilitywiththesystem'soperatingconditions.
