After you pay the freight charge and send us confirmed files, the samples will be ready for delivery in 3-7 days.
The samples will be sent to you via express and arrive in 3~5 days.
Q4: What about the lead time for mass production?
Honestly, it depends on the order quantity and the season you place 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.
