able alarm-blocking with copper tendons, with a polyethylene isolation, in a shell from PV plasti
able alarm-blocking with copper tendons, with a polyethylene isolation, in a shell from PV plasti of the lowered combustibility
CONSTRUCTION
1. CURRENT IS CONDUCTING WIRE from a copper soft round wire by a nominal diameter 0.8, 0.9, 1.0 mm.
2. ISOLATION from polyethylen.
3. TWISTED PAIR in the cables of pair twisting.
4. MANDREL single tendons or pair are twisted up in mandrel.
5. HALF-LENGTH ISOLATION - is a ribbon of polyethylene-tereftalat.
6. A SCREEN - is an aluminium ribbon (on a concordance with a customer). Under a screen a copper contact wire is laid by a nominal diameter 0.4 0.6 mm.
7. SHELL from PV plasti, in cables type of from PV plasti of the lowered combustibility.
APPLICATION DOMAIN
Cables is intended for the electric options of signaling, centralization and blocking, fire warning and automation at nominal voltage 380 V alternating current by frequency 50 Hz. or 700 V direct current, for a gasket in plastic pipelines, in earth, in the conditions of aggressive environment, in default of the mechanical affecting cable.
Cables type of is intended for a single gasket, cables type of for a gasket in bunches.
Cables with current by a conducting tendon 0,8 mm apply a diameter for editing of devices of signaling centralization of blocking only in officially-technical buildings.
