15kV submarine cable manufacturer

The growing demand for marine renewable energy and the electrification of coastal areas have made submarine cables 15 kV are essential in modern electrical projects. And 15kV submarine cable manufacturer must ensure that the cables withstand demanding marine environments, meet international standards and offer reliability for decades.

Submarine cable

What is a submarine cable? 15 kV?

Medium voltage submarine cables are used to transmit electrical energy between islands, offshore wind farms, oil platforms and coastal networks. Besides, These cables must be resistant to hydraulic pressure, marine corrosion and mechanical loads during installation and operation. For this reason, A specialized manufacturer incorporates high-quality materials and performs rigorous testing.

In addition, These cables must meet international standards such as IEC 60228, IEC 60502, IEC 60840 y ASTM, guaranteeing compatibility and security.

Structure of a submarine cable 15 kV

A typical cable 15kV submarine cable manufacturer includes the following layers:

Conductor

The driver can be copper or aluminum, and its section varies according to current needs and applicable regulations. Besides, Material selection influences the electrical resistance and durability of the cable.

Isolation

insulation is used XLPE o EPR, that offer electrical resistance, thermal and chemical. The same way, Provide protection against short circuits and partial discharges.

Screen and metal cover

The semiconductor screen and the lead cover (Lead Sheath) Prevent water ingress and ensure electrical integrity for decades.

armor layer

The armor can be galvanized steel or aluminum wire. This layer provides mechanical resistance against impacts and traction during installation, ensuring the structural integrity of the cable.

External cover

Finally, the outer cover of PE a PVC protects the cable against abrasion, corrosion and environmental factors. Therefore, guarantees durability even in extreme marine conditions.
