“Discontent comes to those who have forgotten how to dream, and those who achieve the fulfillment of their desires find reasons to live.”

An important aspect that ensures the safety and durability of communication structures during operation is the fire protection of cables. These measures are necessary where large cable masses are present and there is an increased risk of fire. The appearance of a fire on cable routes leads to uncontrolled spread of fire. In addition, toxic gases and thick smoke generated during combustion pose a great danger to human health.

Fire retardant coatings used to protect cables must have the following test results:

the length of the flame-damaged or charred part of the cable laying should not exceed 1.5 m;
the reduction factor for the permissible long-term load current for the cable is not less than 0.98;
There should be no cracks, chips or drips on the surface of the fire-retardant cable coating.

When choosing a fire retardant cable covering, the following is important:

thickness of the fire retardant coating declared by the manufacturer: the greater this value, the more layers must be applied, therefore, this work will take more time.
drying after applying the layer takes from 1.5 to 10 hours. Uniform coating of the same thickness can be easily achieved in laboratory conditions. In practice, it is quite difficult to do this in large volumes, so it is necessary to purchase compounds for fire protection work with a certain reserve.
security measures. For a number of compositions, work must be carried out in compliance with safety rules with the voltage turned off in rooms equipped with ventilation, using personal protective equipment. In cases where the work is carried out urgently, you can use certified fireproof fabric.

The effectiveness and service life of fire-retardant cable coating applied to cables largely depends on the quality of fire-retardant work. JSC "VOKS IT" has highly qualified specialists in the field of fire protection of communication cables. For fire protection, certified, environmentally friendly fire retardant paints of the MPVO brand are used. This intumescent fire retardant coating is a product of Research and Production Laboratory No. 38080. The coating is a multicomponent homogeneous viscous suspension of polymers and fillers in an organic solvent - solvent with the addition of fire retardants and flame-extinguishing additives. Layer thickness when applied to cables is 0.8 mm. The coating can be used both outdoors and indoors. Based on the results of checking the state of fire retardant treatment, the Customer receives a complete set of documents.
