Abstract
Electrical cables formed from at least one insulated conductor, a layer of inner armor wires disposed adjacent the insulated conductor, and a layer of shaped strength members disposed adjacent the outer periphery of the first layer of armor wires. A polymeric material is disposed in interstitial spaces formed between the inner armor wires and the layer of shaped strength members, and the polymeric material is further disposed in interstitial spaces formed between the inner armor wire layer and insulated conductor. The polymeric material serves as a continuously bonded layer which also separates and encapsulates the armor wires forming the inner armor wire layer wire layer.
Claims19
A wellbore cable comprising:
- (a) at least one insulated conductor;
- (b) a layer of inner armor wires surrounding the insulated conductor and a layer of shaped strength members disposed adjacent the outer periphery of the first layer of armor wires, the strength members forming a substantially smooth outer surface of the cable;
- (c) a polymeric material disposed in interstitial spaces formed between the inner armor wires and layer of shaped strength members, and interstitial spaces formed between the inner armor wire layer and insulated conductor, the polymeric material at least partially disposed in interstitial spaces formed between shaped strength members, the polymeric material forming a continuously bonded layer which separates and encapsulates the armor wires forming the inner armor wire layer.
