Electrical Cabling Withstands Severe Environmental Conditions 
The problem: 
An electrical cable that can withstand temperatures 
from -150°F to 400°F for long periods, or 1500°F for 
short periods, without losing circuit integrity. The 
cable would also have to perform in severe environ-
mental conditions of vibration and water, and remain 
flexible and abrasion resistant. 
The solution: 
Develop multiconductor electrical cables that are 
heat, vibration, and water resistant. 
How it's done: 
The cable consists of nickel plated copper conduc-
tors; extruded silicone primary insulation for electrical 
integrity; glass braid to hold the primary construction 
together during a fire; and nickel plated copper shield 
and glass braid to add jacket strength and prevent pro-
trusion of the shield through the jacket. The jacket is 
a high strength silicone extrusion which provides the
moisture protection and resistance to mechanical 
abuse.
