The use of lead especially for underground cables is banned due to environmental issues.
Lead in the environment and its effects on the health of people is a matter of great concern to the Agency for Toxic Substances and Disease Registry (ATSDR).
In a report to Congress, The Nature and Extent of Lead Poisoning in Children in the United States, published by ATSDR in July 1988, exposure to lead was identified as a serious public health problem. Soil is contaminated by lead from various sources (American Academy of Pediatrics, 1987). The accumulation of lead in soil is primarily a function of the rate of deposition.
Studies on the effects of lead in children have demonstrated a relationship between exposure to lead and a variety of adverse health effects. These effects include impaired mental and physical development, decreased heme biosynthesis, elevated hearing threshold, and decreased serum levels of vitamin D

What is the meaning of ingress in electrical?
You are probably referring to moisture ingress. Moisture ingress into underground electrical cables, particularly high-voltage cables, can act to break down the insulating properties of that cable, and lead to a short circuit. Accordingly, underground cables incorporate a sheath (lead in older cables), which is impervious to moisture ingress, which surrounds the cable cores, and is located beneath the outer armouring. But moisture ingress can occur with all types of electrical equipment, and the manufacturers take steps to prevent this from happening.

Why earth cable used along with the 11kV power cable?
If you are referring to an 11-kV underground cable, these are normally armoured and, in the case of older cables, have a lead sheath to prevent moisture ingress into the cable. The lead sheath and metal armour are earthed to ensure that, in the event of mechanical damage to the cable, there is a low-resistance path back to the source to sufficient earth-fault current flows in order to operate the circuit's protective system. Overhead lines do not normally have a separate earth conductor.
