Description

The GYTY53 cable is constructed by inserting a 250μm fiber into a loose tube made of a high-modulus material filled with a water-repellent compound. The center of the core is a metal reinforced core. For some cores, a layer of polyethylene (PE) is required to be extruded outside the metal reinforced core. The loose tube (and the filling rope) is twisted around the center reinforcing core into a compact and round core, and the gap in the core is filled with a water blocking filler. The outer core of the cable is extruded with a polyethylene inner sheath, and the double-sided coated steel strip (PSP) is longitudinally wrapped and extruded into a polyethylene sheath to form a cable.

Product Standards

• GYTY53 fiber optic cable complies with YD/T 901 and IEC 60794-1 standards.
Features

Has good mechanical properties and temperature characteristics
The loose tube material itself has good hydrolysis resistance and high strength.
The tube is filled with a special grease to protect the fiber.
Good pressure resistance and softness
The following measures are taken to ensure the waterproof performance of the cable:
- Single wire center reinforcement core
- The loose tube is filled with special waterproof compound
- Full core filling
- Double-sided coated steel strip (PSP) improves the moisture resistance of the cable
- Good water blocking material prevents longitudinal leakage of cable
