26/35kV XLPE Insulation Power Cable

 

Application 

 

The XLPE insulation power cable has excellent hot-mechanical properties,excellent electrical,chemical resistance    properties,also has the advantage of simple structure,light weight,not restricted by the difference of level along the route.Now widely used in urban power grid,mines and chemical plants and other places.
Cable insulation adopt XLPE,use chemical method to linear molecules PE into solid nerwork structure of XLPE,thus substantially improving the mechanical properties of PE,and maintaining the superior ellectrical performance.

 

Construction

 

 Counductor:copper

 Insulation:XLPE

 Sheath:PVC

Technical  Data

 

The long-term working temperature of cable conductor should be not more than 90°C.

While short-circuit the highest working temperature of cable conductor should be not more than 250°C(5 seconds maximum  duration);

The minimum bending radius for laying cable(D is diameter):single core unarmoured cable shoule be 20D,multi-core  unarmoured cable shoule be 15D,single core armoured cable shoule be 15D,multi-core armoured cable should be 12D;

The environment temperature for laying cable should be not less than 0°C.

Notes:1.Ratproof,termite-proof,moisture-proof and other special requiremments cables are available.
2.The single core armoured cable are used for DC system only.As for AC system,non-megnetical materials shoule be used,its corresponding code is 62,63,72,73;
3.It is not recommended AL-core fire retardent cable.When there is a fire,flame temperatures may reach 700°C above due to the meilting point of aluminium is only 660°C,the conductor may be fused;
4.Flame retaradant/fire resistant power cable are available:Representation method of flame retardant grade is the "Z" followed by"A","B","C",such as the "ZA","ZB","ZC".When "ZR" expressed,generally considered to be "C" class of flame retardant.Flame retardant level representation is "ZN" middle "A","B","C",such as the "ZA","ZB","ZC".While using "NH" expressed,it generally considered to be "ZCN".For example;
