Caledonian Cables Ltd has long experience in providing Reeling& Trailing Cables .The material characteristics of Reeling Trailing Cables are as follows:
A. Conductor Screen :
All cables with a voltage rating of 3.3/3.3 KV and above have a cross-linked semiconductor elastomeric material extruded directly over the power core conductor through a triple extrusion process. Textile-reinforced semiconductor tape or water barrier (water-proof) tape can be applied on special request or particular purposes.
B. Insulation Screen :
Semiconductor elastomeric screen: The material used for insulation screen is cross-linked semiconductor elastomeric which directly applied over insulation of each power core.
Textile reinforced semiconductor tape screen: As an alternative to an elastomeric screen, the textile reinforced semiconductor tape screen may be applied over the insulation of power cores of 3.3/3.3kV Type 450 & 451 (Class 1) and 3.3/3.3kV up to and including 11/11kV Type 409 & 440 (Class 2). The semiconductor tape comprises a textile fabric, coated with a semiconductor elastomeric and having a continuous print on one side identifying it as being semiconductor.
C. Cradle separators / Earth Covering / Screen for Core Assembly :
Semiconductor elastomeric used in cradle separators, the interstitial earth conductor covering (other than for Type 412) and the screen for core assembly (Types 241, 245, 275 and 441 only) is a compound based on polychloroprene (PCP) which complies with the table below.
D. Power / Pilot Core Insulation :
Power Core Insulation
AS/NZS 1802 Reeling & Trailing Cables: R-EP-90
AS/NZS 2802 Reeling & Trailing CableS:XP-EP-90
Pilot Core Insulation
AS/NZS 1802 Reeling & Trailing Cables:R-EP-90
AS/NZS 2802 Reeling& Trailing Cables
XP-EP-901/R-EP-90
R-EP-90: a cross-linked compound based on ethylene propylene copolymer, terpolymer or a blend of the two, suitable for up to 90â maximum continuous operating temperature.
XR-EP-90: a cross-linked compound based on ethylene propylene copolymer (EPM), or ethylene propylene terpolymer (EPDM or EPT),having enhanced properties compares with R-EP-90, suitable for up to 90â maximum continuous operating temperature.
E. Metallic Composite Screen :
Composite screen consists of tinned annealed copper interwoven with polyester yarn and each strand consists of seven copper wires with nominal diameter between 0.25 and 0.5mm to form a braid.
F. Pliable Steel Strand Armour :
Pliable amour comprises galvanized low carbon (mild) steel strands, each strand consist of seven wires helically over the inner sheath to provide close cover. The wires comply with the requirements of AS/NZS 3863.
G. Sheath :
Inner sheath (Type 206 and 412 only): GP-85-PCP (Standard), GP-90-CSP or GP-90-CPE to AS/NZS 3803.
Outer sheath:
GP-85-PCP: General purpose cross-linked compound based on Polychloroprene, suitable for up to 85â maximum continuous operating temperature.
GP-90-CSP: General purpose cross-linked compound based on chlorinated polyethylene, suitable for up to 90â maximum continuous operating temperature.
GP-90-CPE: General purpose cross-linked compound based on Chlorosulphonated polyethylene, suitable for up to 90â maximum continuous operating temperature.
HD-85-PCP, HD-90-CSP or HD-90-CPE is the heavy duty version of GP-85-PCP, GP-90-CSP or GP-90-CPE, and XHD is the extra-heavy duty version, the characteristic is as follow:
