Constructional Features:
-
The fiberglass-reinforced polyamide used in manufacture is marked by particulary
high mechanical strength and heat resistance.
-
The dynamic forces of high short-circuit currents are very effectively withstood.
Implementaion can be done in those cases where high short-circuit currents occur.
Therefore a secure fixation of the cables is insured and damage to them is being avoided.
-
Test reports from neutral laboratories concerning dynamic short-circuit currents,
up to 110kA, and the fire-resistance of the material, are available.
-
As the length of the clamping area is very wide the mechanical pressure on the cable is low.
-
Implementation both indoor and outdoor due to resistance to ageing, ozone and ultraviolet rays.
-
No alteration in strength within a temperature range of - 40 °C to 120 °C.
Thus particulary suitable for emergency operations of XLPE insulated cables.
-
Because of its resistance to radioactive rays (at a radiation dose of 100 MRAD
strength loss is less than 20%) implementation is also possible in nuclear power stations.
-
The fastening of cable clamps can be adapted to all local conditions.
