Supporting Clamps for Hanging of
Self-Bearing Items (Like Cables)

Our major customer is ZAO TransTeleCom Company that implements state program to deploy an advanced backbone digital communication network in the Russian Federation by hanging fiber-optic cables onto the current poles of the contact and automatic block systems along railroad tracks of over 35 000 km in total length. We had won the right under the tight competition with domestic and foreign manufacturers of like goods. Our products were recognized as the best in terms of technical design and quality while at minimal cost. The technical council of ZAO TransTeleCom Company approved an Advanced Support Clamp model, which we developed, and since 2001 ZAO TransTeleCom Company has been using only this clamp type in construction of fiber-optic communications.

All models for sale are designed by Ninevia, protected by patents and certified for compliance by the Communication and Informatization Ministry of the Russian Federation that authorizes their mass production at our plant. Besides, our clamp was tested by ERICSSON with a conclusion that "the Russian-manufactured hanger meets all of the Ericsson Cable AB requirements and is allowed to be used with cable products".

The Supporting Clamps are designed for hanging of either domestic or foreign manufactured fiber-optic cables of 10 to 18 mm in diameter onto the poles of contact or automatic block systems of railroad or other networks with the span length of up to 110 m.

The clamp construction includes metal case (aluminum alloy covered with strong protective layer of durable polymer), oil- and petrol resistant rubber bushes of the unique patented composition, and mounting and fastening elements.

At present we have mastered mass production of 3 clamp types: SC (Supporting Clamp), CSC (Supporting Clamp with corrugated rubber bush) and ASC (Advanced Supporting Clamp with corrugated rubber bush). The type is selected to fit the envisaged operational environment.

The clamps have design life of 25 years in operational environment as per 1 UHL Category in GOST 15150-69 Standard, i.e. fit for outdoor usage at temperature range -60 to +55 °C with direct exposure to sun and mechanical impacts like vibration, shock, wind load and icing during winter.

All mass produced clamps are designed for slip force of cable/case of 1.0 to 2.0 kN, and the value can be increased up to 4.0 kN if ordered. The cable outer diameter of 10 to 20 mm shall be specified at the time of order. The manufactured clamps meet technical specifications as follows: TU-3185-001-44338317-98 (for SC and CSC) and TU-3185-002-44338317-2000 (for ASC).

All clamps are patent-protected and certified by the Russian Federation's State Communication Committee.
