Insulating sleeves that keep panel wiring safe
MASCO Electrical PVC Sleeves are used across LT panels, control cabinets, junction boxes and household distribution boards to insulate exposed conductor ends, mark circuits by colour code, and protect crimp lugs. Extruded from virgin PVC compound to hold dielectric strength across seasons, they are rated for 1100 V and remain flexible from -10 °C to +85 °C — the range that covers panel-room and outdoor enclosure temperatures across India.
Full colour range and standard sizes
MASCO sleeves ship in the five standard electrical colours — red, black, blue, yellow and green — for phase identification, neutral, earth and control marking. Sizes cover 4 mm, 6 mm, 8 mm, 10 mm, 16 mm and 25 mm nominal bore, matched to common conductor gauges. Coils are supplied in 30, 50 and 100 metre lengths, poly-bagged and cartoned to keep the sleeving clean and kink-free until it reaches the workshop.
Applications across panels and appliances
Panel builders use MASCO sleeves to insulate copper bus-bar cut ends, mark control circuits and dress crimp terminals. Automotive workshops use short lengths to sleeve battery leads and harness junctions. Electricians on residential jobs use them to sleeve joint boxes and switchboard tails. Because the compound is flame retardant and IS 6746 / IS 10810 tested, MASCO sleeving is accepted on projects that need documented insulation material, and it holds its colour under long UV and heat exposure without fading.
Consistency by the coil
Every batch of MASCO sleeving is dimensionally checked before packing — bore diameter, wall thickness and surface finish are all verified so the sleeve slips over the intended lug in a single motion. The smooth inner surface avoids scoring insulation on the wire, and the outer surface takes a clean marker or heat-print for circuit labelling. Panel builders reordering month after month rely on that consistency to keep their assembly time predictable.
Bulk supply for panel builders and dealers
MASCO supplies electrical sleeves to panel manufacturers, MEP contractors and electrical wholesalers across Kerala and neighbouring states. Bulk cartons and multi-colour combinations can be pre-packed against a purchase order, and repeat customers get scheduled monthly dispatches so their line never stops for the sake of a spool of sleeving.
