Procurement Guide for Optical Power Line Communication Cable ( OPLC ) Filling Strip

(Disclaimer: Some of the information in this article is sourced from the internet. Please carefully identify and use it.)

Product Overview: The filling strip for optoelectronic composite submarine cables is made of polyolefin material, which combines corrosion resistance, high-voltage insulation, and high strength. It is designed specifically for submarine cables to ensure the stability of signal and power transmission.

Key performance indicators (for reference only, not used as procurement standards)

• Insulation performance: Volume resistivity ≥ 1 × 10¹⁴Ω·cm (GB/T 1410 standard).
• Compressive strength:≥ 30MPa, suitable for deep-sea high-pressure environment.
• Salt spray resistance: Passed a 96 hour neutral salt spray test.

Application scenarios

Suitable for underwater optoelectronic composite cables (such as OPGW) and transoceanic communication projects, it can effectively resist seawater corrosion and mechanical stress.

Procurement precautions

• Supplier qualification: Priority should be given to manufacturers with DNV-GL certification.
• Sample testing: A water tightness test is required (maintain a water pressure of 1MPa for 24 hours without leakage).
• Delivery cycle: Confirm whether the manufacturer supports urgent orders (such as delivery within 15 days).

Frequently asked questions

Q: How can filling strips prevent deformation of submarine cables?

A: Select materials with a hardness of ≥ 80 Shore A and ensure that the cross-sectional shape matches the cable core.
