It withstands up to 120℃ and offers over 50 years service life. Available in DB‑N, DB‑R, DB‑E types with diameters 100‑200mm and 4000mm length, customizable. Widely used in power, communication, transportation, airports and infrastructure projects.

Product Introduction

FAQ

1. Product Introduction

FRP Cable Protection Pipe is a professional protective conduit for power and communication cables. Made of high-strength fiberglass reinforced plastic, it is widely used for cable laying under roads, rivers, bridges and other harsh environments. It provides safe, durable and long-term protection for cables with excellent overall performance.

2. Product Features

High strength, light weight (only 1/4 density of steel pipe), easy transportation and installation, no deformation.

Smooth inner wall with low friction, ensures smooth cable pulling without damage.

Non-magnetic, no electric corrosion and no eddy current, ideal for single-core cables.

Good chemical and seawater resistance, insulation, rust-free and maintenance-free.

Heat-resistant up to 120℃, service life more than 50 years.
