Coats Gral Ripcord is the complex thread on a polyester basis developed especially for application as a ripkord in fiber-optical systems. The covering from a protective film has high resistance to attrition and allows to reduce the size of the put ripkord.
Main types of application
- Fiber-optical cable
- It is generally used in production of not reinforced fiber-optical cables
- For optical cables with free laying in a tube, tape cables, cables with the dense buffer and completely dielectric self-bearing cables
Features and advantages
- The unique covering from a protective film provides excellent resistance to attrition
- Reduces the size of the put ripkord
- Threads of standard flowers - natural, red and orange are available
- Threads green, brown and other flowers are made to order
- Flat modification is available
- Waterproof finishing for protection against moisture penetration

Relative lengthening and linear durability are defined according to the test methods described in the ASTM D885 standard
As the choice of threads in many respects depends on conditions and a scope, the producer before production of products should carry out a number of tests of properties of threads to check how chosen threads are suitable for this area of a prmeneniye. The technical characteristics stated above are based on the current average values and can be considered only in common goals as approximate estimates. |

Standard amount of winding:
Standard winding is made on a cone of 94 mm of VD x 216 mm in size (3,7 "VD x 8,5"). However, also other options of winding of threads - a cone of bigger length, other internal diameter, etc. are possible.
