the order.The best record we keep is delivering 10 kilometers cable
within a week. Generally speaking, we suggest that you start
inquiry two months before the date you would like to get the
products at your country.
The 15kV XLPE Insulated Optical Fiber Lead Sheath Steel Wire
Armoured Subsea Power Cable is a specialized high-voltage power
cable designed for subsea applications. It is used to transmit
electrical power over long distances underwater, typically for
offshore oil and gas installations, renewable energy projects, and
other subsea power transmission systems.
Here's a breakdown of its components and features:
Voltage Rating: The cable is rated for a voltage of 15kV,
indicating its capability to handle high voltage levels.
XLPE Insulation: The conductors within the cable are insulated with
XLPE (Cross-Linked Polyethylene). XLPE insulation provides
excellent electrical properties, thermal resistance, and
durability, making it suitable for subsea environments.
Optical Fiber Lead: The cable includes an optical fiber lead, which
allows for data communication or monitoring purposes. This feature
enables the transmission of information alongside the power
transmission, facilitating control and monitoring of the subsea
system.
Lead Sheath: The cable has a lead sheath that surrounds the
XLPE-insulated conductors and optical fiber. The lead sheath acts
as a barrier, protecting the cable's internal components against
moisture, seawater, and mechanical damage.
XLPE (cross-linked polyethylene) insulated cable refers to an
electrical cable that has conductors insulated with XLPE material.
XLPE is a thermosetting polymer known for its excellent electrical
properties, making it a popular choice for various applications in
the power transmission and distribution industry.
