Ship cable MRSHN

Description

Ship cables with copper conductors with insulation of thermoelastoplast, sheath made of oil -gasolin resistant elastomer, fire retardant type NRtSHM, NGRtSHM, MRtSHNE, MERtSHNE are produced by the standard TU 3586-030-24118545-2013 (analogue of GOST 7866.1-70).

Ship cables are produced with new high technology materials replacing all types of rubber and soft PVC, with high elasticity and good chemical, ozone and heat stability, stable in seawater and by low temperatures, nonpolluting, with good dielectric properties.

Ship cables the type NRSHM are used in power and lighting networks, control circuits for connection to fixed and mobile current receivers.  The cables designed for  alternating voltage 690 V and frequency up to 400 Hz or direct voltage 1200 V  with protection from direct sunlight, for fixed laying in seawater under radial hydrostatic pressure up to 1,96 MPa (20 kg/cm2). The cables do not spread fire by the single laying. 

Properties

-  high resistance to mineral oils, fuel, alkalis and acids;

-  wide temperature range of operation: -45 oC up to 125 oC; 

-  temperature of mounting up to -30 oC;

-  low toxicity, no emission  of corrosive gases by burning;

-  low danger to electronic plates

-  good flexibility and resistance to abrasion.
